The document provides an overview of a presentation on designing with data. It outlines the agenda which includes introductions to general theories, quantitative and qualitative data, details of visualization design, and a critique section. The document then delves into each section, providing examples and explanations of concepts like storytelling with data, different graph types, using statistics, qualitative methods, details of design, and suggestions for further references.
Designing with Data: Creating Visualizations to Tell Your Story
1. Welcome to the presentation
on Designing with Data. I
hope you’re excited to learn.
Dominic Prestifilippo | andCulture | Design Methods Training | December 4, 2013
4. introduction
“… 80% of the information
we take in is provided by
our eyesight.”
People are visual learners.

5. Introduction
Visualizations help everyone.
1. Making them provides further insight into the information
2. Visualizations invite comments and inspired discussion
3. Enable presentations that aren’t reliant on scripts or memorization

My interpretation is,
anyone with these names
should hope they have
interesting middle names.
Is that the intent?

Sure it seemed like a
lot before, but you may
have also thought there
was a lot of these other
locations. This helps
highlight the differences
in perception of “a lot.”

Treat each decision as if
it is crucial to the entire
piece, because it is.

Treat each decision as if
it is crucial to the entire
piece, because it is.
I assume the decision to
illustrate this as a sketch
is to make something
potentially scary and
dangerous seem more
approachable.

Average wait times
Juxtaposing relevant data can produce even more interesting results,
highlighting potential relationships and making both data sets more
valuable.

19. General Theories | Layer Information
Average wait times per day is much more interesting

• Does this provide value?
• Does this make sense?
• Can this be done better?
• Does this help convey my message?

“Stacked bar charts
describe totals while
allowing a degree of

of the data.”
“…in a histogram
it is important to
retain and display
the empty space. It
contributes to the
picture of the data
as a whole.”

27. Graph Types | Pie Chart
“…a pie chart can only
represent relative
amounts.”
“The most effective pie
charts comprise only
two items, such as the
percentage of male or
female customers.”
“The total value of the
information must add up to
one hundred per cent…”

“Line graphs work
best when the data
is continuous.”
“Scatter plots are
a useful tool to
reveal relationships
between any amount
of independent
values. …The data
points are placed in
a grid in an attempt
to build a larger
picture.”
“One of most
common variables
used in line graphs
is time…”

“We add together all
of our test results and
then divide it by the sum
of the total number of

“The Median is the
‘middle value’ in

“The mode in a list
of numbers refers to
the list of numbers
that occur most
frequently.”

32. Statements | Highlighting
“Use this to highlight a piece of a quote you would like cited.”

33. Statements | Iconography
Include relevant iconography to help
with wayfinding and make the written
content more memorable

organically depending on

of mapping processes.

38. Details | Data to Pixel Ratio
“the amount of ink
representing the data
divided by the total ink on
the graph”
Don’t be confused; the
data–ink ratio is not
advocating the use of as
little ink as possible, but
only as much ink as needed
to convey the data

39. Details | Chart Junk
“…if you remove something
from the chart and it
doesn’t change the
meaning, it’s chart junk “
Brian Suda, A Practical Guide to Designing with Data, pg 25, 27
40. Details | Resolution
DPI Dots per Inch
For Print Media.
It is preferable that
documents are at least
300dpi.
For Digital Media.
It is preferable that
documents are at least
72dpi.
41. Details | Color
Color can do a lot to help
clarify information on a
chart. However, mis-use
and it will only add to the
confusion.
Be mindful of how you
use color. It can easily be
overdone.
Try starting with black and
white, then adding color
later.
42. Details | Legends
As nice as it can be to have
a very “clean” visualization
or chart, if it doesn’t convey
the necessary information
it is useless.
Make sure, if you do use
distinctions such as
color, shape, size, etc. to
differentiate data, make
sure it is labeled and clear.
