Introduction
Data visualization
The ways we structure and visualize information are
changing rapidly and getting more complex with each
passing day. Thanks to the rise of social media, the
ubiquity of mobile devices, and service digitaliza-
tion, data is available on any human activity that
utilizes technology. The generated information is
hugely valuable and makes it possible to analyze trends
and patterns, and to use big data to draw connections
between events. Thus, data visualization can be an
effective mechanism for presenting the end user with
understandable information in real time.
Data visualization can be essential
to strategic communication: it
helps us interpret available data;
detect patterns, trends, and
anomalies; make decisions; and
analyze inherent processes.
All told, it can have a powerful
impact on the business world.
Every company has data, be it to communicate with
clients and senior managers or to help manage the
organization itself. It is only through research and
interpretation that this data can acquire meaning and be
transformed into knowledge.
This ebook seeks to guide readers through a series of
basic references in order to help them understand data
visualization and its component parts, and to equip
them with the tools and platforms they need to create
interactive visuals and analyze data. In effect, it seeks
to provide readers with a basic vocabulary and a crash
course in the principles of design that govern data visu-
alization so that they can create and analyze interactive
market research reports.
What is data
visualization?
Data visualization is the process of acquiring, interpreting
and comparing data in order to clearly communicate
complex ideas, thereby facilitating the identification and
analysis of meaningful patterns.

The data
visualization process
Several different fields are involved in the data visual-
ization process, with the aim of simplifying or revealing
existing relationships, or discovering something new
within a data set.
Visualization process
1
Filtering & processing. Refining and cleaning data to
convert it into information through analysis, interpreta-
tion, contextualization, comparison, and research.
Translation & visual representation. Shaping the
visual representation by defining graphic resources,
language, context, and the tone of the representation,
all of which are adapted for the recipient.
Perception & interpretation. Finally, the visualization
becomes effective when it has a perceptive impact on
the construction of knowledge.

Why is data
visualization so
important in reports
and statements?
We live in the era of visual information, and visual
content plays an important role in every moment of
our lives. A study by SH!FT Disruptive Learning demon-
strated that we typically process images 60,000
times faster than a table or a text, and that our brains
typically do a better job remembering them in the long
term. That same research detected that after three days,
analyzed subjects retained between 10% and 20% of
written or spoken information, compared with 65% of
visual information.
The rationale behind the power
of visuals:
• The human mind can see an image for just 13 mil-
liseconds and store the information, provided that
it is associated with a concept. Our eyes can take in
36,000 visual messages per hour.
• 40% of nerve fibers are connected to the retina.
All of this indicates that human beings are better at
processing visual information, which is lodged in our
long-term memory.
Consequently, for reports and statements, a visual rep-
resentation that uses images is a much more effective
way to communicate information than text or a table; it
also takes up much less space.
This means that data visuals are more attractive,
simpler to take in, and easier to remember.
Try it for yourself. Take a look at this table:
Identifying the evolution of sales over the course of the
year isn’t easy. However, when we present the same
information in a visual, the results are much clearer (see
the graph below).
The graph takes what the numbers cannot communi-
cate on their own and conveys it in a visible, memorable
way. This is the real strength of data visualization.

Graphical excellence is that which gives to
the viewer the greatest number of ideas in
the shortest time with the least ink in the
smallest space.”
- Edward Tufte (2001)

Data visualization chiefly helps in 3 key aspects of
reports and statements:
1) Explaining
Visuals aim to lead the viewer down a path in order to describe situations, answer
questions, support decisions, communicate information, or solve specific problems.
When you attempt to explain something through data visualization, you start with a
question, which interacts with the data set in such a way that enables viewers to make
a decision and, subsequently, answer the question.
For example: This graphic below could clearly explain the country with the greatest
demand for a certain product compared globally, in a concrete month.
For example: an interactive graphic from The Guardian2
invites us to explore how the
linguistic standard of U.S. presidential addresses has declined over time. The visual is
interactive and explanatory, in addition to indicating the readability score of various
presidents’ speeches.
3) Analyzing
Other visuals prompt viewers to inspect, distill, and transform the most significant
information in a data set so that they can discover something new or predict upcom-
ing situations.
For example: this interactive graphic about learning machine3
invites us to explore
and discover information within the visual by scrolling through it. Using the machine
learning method, the visual explains the patterns detected in the data in order to cate-
gorize characteristics.
We’ll close this introduction with a 2012 reflection by Alberto Cairo, a specialist in
information visualization and a leader in the world of data visualization. For the
author, a good visual must provide clarity, highlight trends, uncover patterns, and
reveal unseen realities:
We create visuals so that users can analyze data and, from it, dis-
cover realities that not even the designer, in some instances, had
considered.”

2) Exploring
Some visuals are designed to lend a data set spatial dimensions, or to offer numerous
subsets of data in order to raise questions, find answers, and discover opportunities.
When the goal of a visual is to explore, the viewers start by familiarizing themselves
with the dataset, then identifying an area of interest, asking questions, exploring, and
finding several solutions or answers.

Data types,
relationships, and
There are a number of methods and approaches to
creating visuals based on the nature and complexity
of the data and the information. Different kinds of
graphics are used in data visualizations, including
representations of statistics, maps, and diagrams.
These schematic, visual representations of content
vary in their degree of abstraction.
In order to communicate effectively, it is important to
understand different kinds of data and to establish
visual relationships through the proper use of graphics.
Enrique Rodríguez (2012), a data analyst at DataNauta,
once explained in an interview that...
2) Qualitative (categoric)
This kind of data is divided into categories based on
non-numeric characteristics. It may or may not have a
logical order, and it measures qualities and generates
categorical answers. It can be:
• Ordinal: Meaning it follows an order or sequence.
That might be the alphabet or the months of the year.
• Categorical: Meaning it follows no fixed order. For
example, varieties of products sold.
2 kinds of data
Before we talk about visuals themselves, we must first understand the different
kinds of data that can be visualized and how they relate to one another.
Quantitative Qualitative
A good graphic is one that synthesizes
and contextualizes all of the information
that’s necessary to understand a situa-
tion and decide how to move forward.”
The most common kinds of data are4
:
1) Quantitative (numeric)
Data that can be quantified and measured. This kind of
data explains a trend or the results of research through
numeric values. This category of data can be further
subdivided into:
• Discrete: Data that consists of whole numbers (0, 1, 2,
3...). For example, the number of children in a family.
• Continuous: Data that can take any value within an
interval. For example, people’s height (between 60 -
70 inches) or weight (between 90 and 110 pounds).

7 data relationships
Data relationships can be simple, like the progress of a single metric over time (such as visits to a blog over the course of 30 days or the number of users on a social network),
or they can be complex, precisely comparing relationships, revealing structure, and extracting patterns from data. There are seven data relationships to consider:
Ranking: A visualization that relates two or more values
with respect to a relative magnitude. For example: a
company’s most sold products.
Deviation: Examines how each data point relates to the
others and, particularly, to what point its value differs
from the average. For example: the line of deviation for
tickets to an amusement park sold on a rainy versus a
normal day.
Correlation: Data with two or more variables that can
demonstrate a positive or negative correlation with one
another. For example: salaries based on level of education.
Distribution: Visualization that shows the distribu-
tion of data spatially, often around a central value.
For example: the heights of players on a basketball team.
Partial and total relationships: Show a subset of data
as compared with a larger total. For example: the per-
centage of clients that buy specific products.
Nominal comparisons: Visualizations that compare
quantitative values from different subcategories. For
example: product prices in various supermarkets.
Series over time: Here we can trace the changes in the
values of a constant metric over the course of time. For
example: monthly sales of a product over the course of
two years.

There are two types of visualizations: static and
interactive. Their use depends on the search and
analysis dimension level. Static visuals can only
analyze data in one dimension, whereas inter-
active visuals can analyze it in several.
As with any other form of communication, familiar-
ity with the code and resources that are available to
us is essential if we’re going to use them successfully
our goal. In this page, we present the different kinds
of graphics that we can use to transform our data
into information. This group of visualization types
is listed in order of popularity in the “Visualization
Universe” project by Google News Lab and Adioma,
as of the publication of this report.
1. Bar chart
Bar charts are one of the most popular ways of visual-
izing data because they present a data set in a quickly
understood format that enables viewers to identify
highs and lows at a glance.
Vertical column
Used for chronological data, and it
should be in left-to-right format.
Horizontal column
Used to visualize categories.
Full stacked column
Used to visualize categories that
collectively add up to 100%.

They are very versatile, and they are typically used
to compare discrete categories, to analyze changes
over time, or to compare parts of a whole.
The three variations on the bar chart are:

3. Pie charts
Pie charts consist of a circle divided into sectors, each
of which represents a portion of the total. They can
be subdivided into no more than five data groups. They
can be useful for comparing discrete or continuous data.
The two variations on the pie chart are:
• Standard: Used to exhibit relationship between parts.
• Donut: A stylistic variation that facilitates the inclu-
sion of a total value or a design element in the center.

2. Histograms
Histograms represent a variable in the form of bars,
where the surface of each bar is proportional to the
frequency of the values represented. They offer an
overview of the distribution of a population or sample
with respect to a given characteristic.
The two variations on the histogram are:
• Vertical columns
• Horizontal columns

4. Scatter plots
Scatter plots use the spread of points over a Car-
tesian coordinate plane to show the relationship
between two variables. They also help us determine
whether or not different groups of data are correlated.
5. Heat maps
Heat maps represent individual values from a data
set on a matrix using variations in color or color
intensity. They often use color to help viewers com-
pare and distinguish between data in two different
categories at a glance. They are useful for visualizing
webpages, where the areas that users interact with most
are represented with “hot” colors, and the pages that
receive the fewest clicks are presented in “cold” colors.
The two variations on the heat map are:
• Mosaic diagram
• Color map

6. Line charts
These are used to display changes or trends in data
over a period of time. They are especially useful for
showcasing relationships, acceleration, deceleration,
and volatility in a data set.
7. Bubble charts
These graphics display three-dimensional data and
accentuate data in dispersion diagrams and maps.
Their purpose is to highlight nominal comparisons and
classification relationships. The size and color of the
bubbles represent a dimension that, along with the
data, is very useful for visually stressing specific values.
The two variations on the bubble chart are:
• The bubble plot: used to show a variable in three
dimensions, position coordinates (x, y) and size.
8. Radar charts
These are a form of representation built around a
regular polygon that is contained within a circle,
where the radii that guide the vertices are the axes
over which the values are represented. They are
equivalent to graphics with parallel coordinates on polar
coordinates. Typically, they are used to represent the
behavior of a metric over the course of a set time cycle,
such as the hours of the day, months of the year, or days
of the week.

9. Waterfall charts
These help us understand the cumulative effect
of positive and negative values on variables in a
sequential fashion.
10. Tree maps
Tree maps display hierarchical data (in a tree struc-
ture) as a set of nested rectangles that occupy sur-
face areas proportional to the value of the variable
they represent. Each tree branch is given a rectangle,
which is later placed in a mosaic with smaller rectangles
that represent secondary branches. The finished prod-
uct is an intuitive, dynamic visual of a plane divided into
areas that are proportional to hierarchical data, which
has been sorted by size and given a color key.

11. Area charts
These represent the relationship of a series over
time, but unlike line charts, they can represent
volume. The three variations on the area chart are:
• Standard area: used to display or compare a pro-
gression over time.
• Stacked area: used to visualize relationships as part
of the whole, thus demonstrating the contribution of
each category to the cumulative total.
• 100% stacked area: used to communicate the dis-
tribution of categories as part of a whole, where the
cumulative total does not matter.
Selecting the right graphic to effectively communicate
through our visualizations is no easy task. Stephen
Few (2009), a specialist in data visualization, proposes
taking a practical approach to selecting and using an
appropriate graphic:
• Choose a graphic that will capture the viewer’s
attention for sure.
• Represent the information in a simple, clear, and
precise way (avoid unnecessary flourishes).
• Make it easy to compare data; highlight trends
and differences.
• Establish an order for the elements based on the
quantity that they represent; that is, detect maxi-
mums and minimums.
• Give the viewer a clear way to explore the
graphic and understand its goals; make use of
guide tags.

data visualization
Shneiderman introduces his famous mantra on how
to approach the quest for visual information, which he
breaks down into three tasks:
1. Overview first: This ensures viewers have a general
understanding of the data set, as their starting point for
exploration. This means offering them a visual snapshot
of the different kinds of data, explaining their relation-
ship in a single glance. This strategy helps us visualize the
data, at all its different levels, at one time.
2. Zoom and filter: The second step involves supple-
menting the first so that viewers understand the data’s
underlying structure. The zoom in/zoom out mechanism
enables us to select interesting subsets of data that meet
certain criteria while maintaining the sense of position
and context.
3. Details on demand: This makes it possible to select
a narrower subset of data, enabling the user to interact
with the information and use filters by hovering or click-
ing on the data to pull up additional information.
The chart on the right side summarizes the key points to
designing such a graphic, with an eye to human visual
perception, so that users can translate an idea into a set
of physical attributes.
These attributes are: structure, position, form size,
and color. When properly applied, these attributes can
present information effectively and memorably.

Graphics with
an objective: seeking
your mantra
The goal of data visualizations is to help us understand
the object they represent. They are a medium for com-
municating stories and the results of research, as well
as a platform for analyzing and exploring data. There-
fore, having a sound understanding of how to create
data visualizations will help us create meaningful and
easy-to-remember reports, infographics, and dash-
boards. Creating suitable visuals helps us solve problems
and analyze a study’s objects in greater detail.
The first step in representing information is trying
to understand that data visualization.
Ben Shneiderman gave us a useful starting point in his
text “The Visual Information-Seeking Mantra” (1996),
which remains a touchstone work in the field. This
author suggests a simple methodology for novice users
to delve into the world of data visualization and experi-
ment with basic visual representation tasks.5

Furthermore, the visual hierarchy of elements plays a
role in this encoding process, because the elements’
organization and distribution must have a well-defined
hierarchical system in order to communicate effec-
tively (Meirelles: 2014). In a sense, visualizations are
paragraphs about data, and they should be treated
as such. Words, images, and numbers are part of the
information that will be visualized. When all of the
elements are integrated in a single structure and visual
hierarchy, the infographic or report will organize space
properly and communicate effectively, according to
your user’s needs.
Layout and design:
communicative
elements
In order to begin designing our reports and state-
ments, it is essential to understand that visual repre-
sentations are cognitive tools that complement and
strengthen our mental ability to encode and decode
information6
. Meirelles (2014) notes that: “All graphic
representation affects our visual perception,
because the elements of transmission utilized act
as external stimuli, which activate our emotional
state and knowledge.”
Thus, when our mind visualizes a representation, it
transforms the information, merges it, and applies a
hierarchical structure to it to facilitate interpretation.
For this reason, in order to have an efficient per-
ceptive impact, it is important to adhere to a series
of best practices when creating reports and info-
graphics. As with any other form of communication,
success depends largely on the business’s familiarity
with the established code and the resources available.
Space, shapes, color, icons, and typography are a
few of the essential elements of a striking visual with
communicative power.
6 Meirelles, I (2014). “La información en el diseño,” (p.21-22). Barcelona: Parramón.
Structuring: the importance
of layout
All visual representations begin with a blank dimensional
space that will eventually hold the information which
will be communicated. The process of spatial coding is
a fundamental part of visual representation because it
is the medium in which the results of our compositional
decisions and the meaning of our visual statement will
be visualized, thereby having an impact on the user.
Edward Tufte (1990) defines “layout” as a scheme for
distributing visual elements in order to achieve organi-
zation and harmony in the final composition. Layout
planning and design serve as a template for applying
hierarchy and control to information at varying levels of
detail.7
In his book Envisioning Information, Tufte offers
several guidelines for information design:
• Have a properly chosen format.
• Give a broad visual tour and offer a focused reading
at different detail levels.
• Use words, numbers, and drawings.
• Reflect a balance, a proportion, a sense of relevant
scale, and a context.
Spatial encoding requires processing spatial proportions
(position and size), which have a determining role in the
organization of perception and memory.

Visual variables
and their semantics
Visual variables are the building blocks of visual repre-
sentation. They conform to an order and spatial con-
text in order to convey a quantitative message. These
resources can be used to categorize meaningful prop-
erties and amplify the message being represented. Let’s
take a look at their semantics:
• Point: Has no dimensions and indicates a place.
• Line: Has one dimension and indicates length
and direction.
• Plane: Has two dimensions and indicates space
and scale.
Jacques Bertin, cited in Meirelles (2014), used the term
“visual variables” for the first time in his book Semiol-
ogie Graphique, where he presented them as a system
of perceptive variables with corresponding properties
of meaning. He offered a guide for combining graphic
elements in an appropriate way according to their order,
position, orientation, size, texture, and value.

Using consistent and attractive
color schemes
Color is one of the most powerful resources for data
visualization, and it is essential if we are going to under-
stand information properly.
Color can be used to categorize elements, quantify
or represent values, and communicate cultural attri-
butes associated with a specific color.
It dominates our perception and, in order to analyze it,
we must first understand its three dimensions.
Hue: this is what we normally imagine when we picture
colors. There is no order to colors; they can only be dis-
tinguished by their characteristics (blue, red, yellow, etc.).
Brightness: the color’s luminosity. This is a relative mea-
sure that describes the amount of light reflected by one
object with respect to another. Brightness is measured
on a scale, and we can talk about brighter and darker
values of a single hue.
Saturation: this refers to the intensity of a given color’s
hue. It varies based on brightness. Darker colors are less
saturated, and the less saturated a color is, the closer
it gets to gray. In other words, it gets closer to a neutral
(hueless) color. The following graphic offers a brief sum-
mary of color application.

Isabel Meirelles (2014) notes that selecting a color pal-
ette in order to visualize data is no easy task, and she
recommends following Cynthia Brewer’s advice uses
three different kinds of color schemes, based on the
nature of the data:
1. Monochromatic sequential palettes or
their analogue
These palettes are great for ordering numeric data that
progresses from small to large. It is best to use brighter
color gradients for low values and darker ones for
higher values.
2. Diverging palettes
These are more suitable for ordering categorical data,
and they are more effective when the categorical
division is in the middle of the sequence. The change in
brightness highlights a critical value in the data, such as
the mean or median, or a zero. Colors become darker to
represent differences in both directions, based on this
meaningful value in the middle of the data.
Thus, brightness levels can be used as a visible, coherent
aspect of a graphic scheme. Sequential color schemes
make it possible to create a smooth, low-contrast
design. This color scheme is better for an image than for
data visualization.
TIP: Try to emphasize the most important information
using arrows and text, circles, rectangles, or contrasting
colors. This way, when you visualize your data, your
analysis will be more understandable.
3. Qualitative palettes
These are better for representing ordinal or categorical
data to create primary visual differences between catego-
ries. Most qualitative schemes are based on differences in
hue, with differences in brightness between the colors.
TIP: To create a color hierarchy in a sequential scheme,
choose one dominant color and use the others with
moderation; alternatively, you can simply use two softer
versions of the dominant color, which will naturally
make them feel lower on the hierarchy.
TIP: The qualitative color scheme is perfect for visualiz-
ing data because it affords a high degree of contrast and
helps you draw attention to important points, especially
if you use one predominant color and use the second as
an accent in your design.
Finally, don’t forget to use palettes that are comprehen-
sible to people who can’t see color. Color blindness is a
disability or limited ability that makes it difficult to distin-
guish certain pairs of colors, such as blue and yellow, or
red and green. One strategy for avoiding this problem is
to adapt designs that use more than just hue to codify
information; create schemes that slightly vary another
channel, such as brightness or saturation.

Use icons and symbols to aid
in understanding and limit
unnecessary tagging
Symbols and icons are another avenue for visualizing
information that goes beyond merely being decorative.
They draw strength from their ability to exhibit a gen-
eral context in an attractive, precise way. Icons illustrate
concepts. Viewers can understand what the information
is about by just glancing at the illustration.
Alexander Skorka (2018), chief evangelist for the Dapresy
Group, recommends using symbols and icons because
they simplify communication. Symbols are self-ex-
planatory, and our mind can process icons more
easily than text. It is important to consider that an
icon’s success depends largely on cultural context, so it is
important to select universally understandable images.
That said, they certainly should not be complex illustra-
tions. An icon with too many details could hinder viewers’
understanding. Keep it simple: icons’ meaning should be
immediately clear, even when they’re very small.
The ease with which we recognize icons enables us to
process data faster than we can process information
conveyed textually. Therefore, when designing informa-
tion, it is wise to use both graphics and icons to convey
proportions in greater detail.

The typography in our reports:
effective applications
Typography plays an important role in the design
of reports and statements. Selecting the right font
strengthens your message and captures the audience’s
attention. Müller-Brockmann (1961), a graphic designer,
defines typography as the proper visual element for
composition. He notes that “the reader must be able to
read the message from a text easily and comfortably.
This depends largely on the size of the text, the length of
the lines, and the spacing between the lines”.8
Typography is an art form in and of itself, in which
every font has its own characteristics, which should
be strategically combined.
For people outside the world of graphic design, choos-
ing a font and setting other typographical features can
be tricky, but it doesn’t have to be. Let’s take a practical
look at the steps you should take when determining
your typography, and then consider the images and
visual elements that best accompany your text. Consid-
erations when setting your typography:
• Determining the goal of your report’s content.
• Select a font that strengthens that goal.
Fonts come in two types: with serifs or without (sans)
serifs. Serif fonts have an extra stroke that conveys a
8 The Graphic Artist and his Design Problems (Gestaltungsprobleme
des Grafikers), Teufen, 1961
sense of tradition, security, history, integrity, author-
ity, integrity, and other such concepts. Sans-serif
fonts stand out because they have a more polished,
sophisticated feel; they convey a sense of modernity,
order, cleanliness, elegance, avant-garde, and style.
• Pay attention to legibility. Remember that screen
type does not appear in the same way as print type.
It is best to choose a more responsive (sans-serif) font
for on-screen texts, and fonts with serifs for printed
reports. That said, there’s an exception to every rule,
and today there is a bounty of fonts that are perfectly
suitable for both digital and print media.
• Watch your weight (light, regular, bold). When
it comes to bolding your text, a value of two or three
should be plenty. It is better to reserve the heaviest
weight for headlines and then apply a stylistic hierar-
chy based on your content. Avoid fonts that only offer
one weight or style, since their applications are limited.
• Don’t forget that some fonts use more memory
than others. Fonts with serifs generally monopolize
more of your computer’s brain power than sans-serif
fonts. This is an important consideration in interactive
reports, since a document that occupies more RAM
will be less responsive.
Fonts have personalities that help us establish a more
attractive visual tone for our audience. Familiarizing
yourself with a few can go a long way. There are:
• Professional fonts
• Fun font
• Handwritten fonts
• Minimalist fonts

Prioritize patterns in your visualizations: Gestalt
The basic elements of the visualization process also involve preattentive attributes. Preattentive attributes are visual
features that facilitate the rapid visual perception of a graphic in a space. Designers use these characteristics to
better uncover relevant information in visuals, because these characteristics attract the eye.
Colin Ware, Director of the Data Visualization Research Lab at the University of New Hampshire, has highlighted
that preattentive attributes can be used as resources for drawing viewers’ immediate attention to certain
parts of visual representations (2004). According to Ware, preattentive processing happens very quickly—typi-
cally in the first 10 milliseconds. This process is the mind’s attempt to rapidly extract basic visual characteristics from
the graphic (stage 1). These characteristics are then consciously processed, along with the perception of the object,
so that the mind can extract patterns (stage 2), ultimately enabling the information to move to the highest level of
perception (stage 3). This makes it possible to find answers to the initial visual question, utilizing the information
saved in our minds. Colin Ware, cited in Meirelles (2014), explains it as follows:
Preattentive attributes enhance object perception and cognition processes, leveraging our mind’s visual capacities.
Good data visualizations deliberately make use of these attributes because they boost the mind’s discovery and rec-
ognition of patterns such as lines, planes, colors, movements, and spatial positioning.9

Detecting patterns is fundamental to structuring and
organizing visual information. When we create visuals,
we often want to highlight certain patterns over others.
Preattentive attributes are the alphabet of visual lan-
guage; analytic patterns are the words that we write
by using them. When we see a good visualization, we
immediately detect the preattentive attributes and rec-
ognize analytic patterns in the visualization. The follow-
ing table summarizes a few basic analytic patterns:

According to Dondis (2015), Gestalt’s principles help
describe the way we organize and merge elements
in our minds. They quiet the noise of the graphics so
that we relate, combine, and analyze them. These
principles come into play whenever we analyze any
sort of visualization. Only position and length can be
used to accurately perceive quantitative data. The
other attributes are useful for perceiving other sorts
of data, such as categorical and relational data.
We’ll close this section with one piece of practical
advice on how to effectively visualize data. Colin
Ware in The Visual Thinking: for Graphic Design
(2008) summarizes the importance of always being
mindful of preattentive attributes and patterns when
designing a visualization:
Gestalt’s principles
Good design optimizes the visual thinking process.
The choice of patterns and symbols is important so
that visual queries can be efficiently processed by
the intended viewer. This means choosing words
and patterns each to their best advantage.”
28
We have seen how preattentive attributes and patterns
make it possible to process and analyze visual informa-
tion; they also enable us to improve pattern discovery
and perceptive inferences and provide processes for
solving visualization problems.
Gestalt’s principles are the principles that enable us to
understand the requirements posed by certain prob-
lems so that we see everything as an integral, coherent
whole. It involves proximity, similarity, shared destiny,
“pragnanz” or pithiness, closure, simplicity, familiarity,
and discernment between figure and ground.

Storytelling for social and

Storytelling for
social and market
communication
The triune model is a valuable tool for effectively com-
municating with our audience. It is one of many theories
employed in neuromarketing to influence and persuade
potential buyers. Understanding and mastering this
theory enables us to extract information not just from
the neocortex, but from the reptilian and emotional
brains as well. This can be useful for qualitative market
research methodology, since it utilizes a host of different
techniques, including in-depth interviews, ethnographic
research, and focus groups. This information is essential
if we are aiming towards a scientific framework to talk
about neuromarketing.
How, then, can we create stories that use data to
communicate insights? Below, we explain three simple
sequences for telling a story:
• Influencing people’s emotions by telling a story
(drawing in their attention).
• Persuading them through benefits that cover specific
needs (benefits/engagement).
• Moving on to concrete steps (call to action).
If you can successfully visualize this sequence, you
understand the foundation of all narratives. What that
means is that every story we try to tell has a beginning,
a developed plot, and a resolution, all building up to
the invaluable call to action. If you have a clear notion
of how to include the “story” element in your reports,
statements, and dashboards, you will successfully create
stories that use your data to share insights.
As we saw at the beginning of this ebook, our mind
tends to visualize information in order to satisfy a basic
need: telling a story. It is one of the most primitive
forms of communication, and it is inherent in every
human being.
We cannot live
without communicating,
without expressing our
personalities, emotions,
and moods, our worries
and fears.
Paul Maclean, cited in María Alejandra Rendón (2009),
proposes a “Triune brain” theory, which addresses
the structure and behavior of the human mind. For
Maclean, the mind consists of three inseparable parts
(or distinct brains); none of the three functions inde-
pendently or separately. They are the reptilian brain, the
emotional brain, and the neocortex.
The reptilian brain is home to our unconscious, also
known as our instinctive side. It manages survival and
our body’s self-regulation. The second part, the emo-
tional brain, is responsible for our emotional processes
and basic motivations. Last but not least, the neocor-
tex is our more rational, complex side. It is in charge of
driving our systematic and logical thinking.

Data storytelling
We all love good stories, and data is one of the best
tools for telling them. Millions of pieces of data are
generated every day. They could be converted into
great stories, but instead they are left unused. It’s time to
change all that. It’s time to start telling stories that draw
their power from data.
So-called “data storytelling” is nothing more than
placing a structured focus on the way we use data to
communicate insights. It relies on three key elements:
narrative, visualization, and data.
Data + Narrative
Data can be insights; they are drawn from study and
analysis. Their nature can propose the narrative context.
Visualization + Data
Visualization shines a light on our data by enabling us to
rapidly process large volumes of data in a visual system.
As more data series are represented, we rely less on the
verbal and more on the visual. Thus, we can enlighten
our audience with insights that they may not have oth-
erwise seen
Narrative + Visualization
The story must motivate. It must have a plot, highs and
lows, and an arc of emotional connection in order to
draw in and entertain our audience.
The perfect combination
Data + Visualization + Narration =
Successfully using our data to tell a
story, wield influence, and effect the
desired change.
What do we get when we
combine these elements?

In case you don’t have a clear notion of how to include the “story”
element in your data, we’re going to outline a few points that will
guide you, so that your presentations and reports manage to grab
your audience’s attention and have a major impact:
1. Find the story in your data. Write, write, and
write. Write about the highlights of your research in different roles.
Worry about presentation later.
2. Define the perspective. Who are you talking to?
What’s the best way to achieve your objective?
3. Create a hierarchy. What is the most important
thing you are trying to convey? Establish different depths to your
reading and data. Avoid irrelevant information.
4. Organize. Figure out the most suitable sequence for
presenting your data. What relationships can you establish
between different aspects of your data? What do some pieces of
data mean relative to others? Are they the framework (data that
reveals), the details (data that delves deeper), or the contrast (data
that dramatizes differences)?
5. Plot. Generate interest; create tension. Depict the concept,
crux, and resolution. Incentivize your audience to keep reading
until the last page, so to speak. Establish relationships.
6. Use data to anchor your narrative. The
story in your data ought to be simple; the vision drawn from the
data comes with an implicit responsibility to be sincere and honest.
7. Design principles. Adhere to the best practices of
design to visualize your data.
8. Review, review, review. Make sure that all of your
analysis is precise.
9. Be familiar with your content and
respect your audience.
10. Keep it short and sweet. Data-based storytell-
ing is the product of hours of work. It’s best to keep presentations
short, with concrete ideas adapted to the audience so that your
message is conveyed efficiently and smoothly.

presentations and final reports

Data visualization technologies and methods continue
to evolve in important ways. This cutting-edge report
reflects the most relevant alternatives available on the
market that can be used to work in this field. In both
the software industry and the academic sector, sev-
eral paths for innovation and development are at the
forefront, including: scrollytelling, social-first data
visualitzation, and virtual reality vizualisations.
Scrollytelling
“Scrollytelling” is a technique that we’ve all experi-
enced first-hand when viewing certain infographics or
websites. As the name implies, it aims to tell a story
as users scroll through a graphic. There are many
libraries that can help generate this kind of visualiza-
tion, including Waypoints, ScrollStory, ScrollMagic, and
Graph-Scroll.js
These tools enable users to interact with content as they
scroll through a webpage or zoom in on content, which
changes and tells a story. By interacting with the visual-
ization of the data, users can see more details, a timeline,
or new elements, such as text, icons, or graphics. Russel
Goldenberg, an expert in data and visualization, once
explained how to implement this technique on his blog,
expounding on the characteristics, advantages, and
disadvantages of various graphic libraries whose code is
intended to act as the foundation for this sort of project.
Social-first data
visualization
The landscape of data visualization is constantly chang-
ing, as we have seen throughout this report. Needless to
say, social networks now play an important role, since
the constant flow of information enables us to draw
more and more narrative stories from data obtained by
Instagram, Snapchat, and YouTube. RJ Andrews, in his
work “Info We Trust”, notes that “It’s almost like con-
tent stumbles onto social right now.” He adds that, “it is
something that has yet to be figured out in a compel-
ling way, but the community is slowly becoming aware.
Social can mean a lot of things” for the market and for
market research.
It seems that RJ is not alone. UX designer and data
enthusiast Catherine Madden expects to see more
“snackable” visual content in 2017: “I want to see some-
thing that can be consumed on an Instagram feed that
might hook someone into learning more that is also easy
to share.”
One great example of such an influencer is Mona Chal-
abi, Data Editor at Guardian U.S., who has over 50,000
Instagram followers. She has published a series of active
content visualizations on gender, consumption, politics,
and so on. Checking out her profile is “required reading”
for anyone interested in learning about data visualiza-
tion and social media.
The diversity of information has led to the emergence of
tools that help us uncover—through published images—
conversations about a given brand that are taking place
online on a daily basis. One such tool is Brandwatch,
a social intelligence platform for unearthing key ideas
that are being discussed in the billions of conversations
taking place online. This technique enables us to reveal
key information about the consumer’s individualized
online experience.

Virtual reality
visualizations
Virtual reality has the potential to revolutionize data
visualization, especially when it comes to big data.
Even in a two-dimensional image, there is already too
much data for the human eye to capture. Now imagine
a three-dimensional data visualization, which allows
the user to fully interact with data in a 360-degree field
of vision.
Virtual reality data visualizations are highly interactive,
computer generated 3D projections. Although the
concept of virtual reality is nothing new, the idea of
immersive data exploration certainly is, and the exciting
possibilities that it promises are endless.
What does the future
have in store?
Visual data representation techniques and methods
progress every day, as technology evolves and our body
of theoretical knowledge grows. As this technology
and this knowledge work in tandem, we will continue
developing solutions for our problems and needs. From
this report, we hope you have deduced that, in our
current era, images are the most efficient language. We
hope you now understand that tools and software can
help us discover limitless graphic resources and develop
new structures for communicating and conveying ideas.
Consequently, we can confidently state that the applica-
tions of graphic representation are constantly expand-
ing, and we must not forget that they are the objective
of our communication strategies in market research.
