Why Visualization?

Why visualization?

Visualization makes data accessible.

Visualization allows access to huge amounts of data.

Why extensible visualization?

The old way…

The new way…

The Upside of Flexibility

When are visualizations successful?

1.  purpose – why this visualization 2.  content – what to visualize 3.  structure – how to visualize it 4.  formatting – everything else

A Successful Visualization

Purpose > Content > Structure > Formatting

• Why am I creating this visualization?

• Who is it for?

• What do they need to understand?

• What actions do you need to enable?

• How will it be consumed?

Purpose dictates the deliverable. Different destinations require different maps.

http://maps.google.com

• What data matters? • What relationships matter? • Informed by purpose! • What’s excluded is as important as what’s included.

http://demographics.coopercenter.org/DotMap/index.html

• How do we best reveal the most important data and relationships?

• Choose meaningful layout and axes! • Use both axes! (Both, not three…) • Informed by purpose and content!

Structure fail.

Structure fixed.

• How should it look and feel? • How will it be consumed? • Makes data and relationships accessible.

• Makes importance visible. • Informed by purpose, content, and structure!

Formatting

Structure

Content

Purpose

Creating effective visualizations Choosing the right visual properties Learn how to properly choose the visual property (position, shape, size, color and others) to encode the different types of data that will be presented in a visualization.

• Is the purpose well-defined? • Does the content support the purpose?

• Does the structure reveal the content? • Does the formatting facilitate consumption?

• Iterate, iterate, iterate…

Perceptions & Questions

Analyst: Robin Bloor

Minard’s Visualization

Dimensions: Advance/retreat (color), geographical location, number of men, temperature, distance & time

Tables and Dimensions

The problems with“unvisualized” data:

u  Every column in a table is a dimension

u  Time is a critical dimension

u  Some dimensions have high variability (say 00.00 to 1,000,000.00), others low variability (male/female), others are descriptors or UIDs

u  A table is possibly the worst way to represent data helpfully – although you can do things with a table (counts, averages, etc.)

u  It’s a very good way to store data

Information Service

There are many reasons why data may be provided to people:

u  To inform or alert them

u  To motivate them

u  To entertain them

u  To assist them (assist decisions)

u  To empower them (or evaluate them?)

u  To educate them (or help them self-educate)

THE CONTEXT DETERMINES THE INFORMATION SERVICE AND ITS CHARACTER

Consumers & Explorers

SPECIFIC USER

TYPES:

Needs to be informed and/or enabled in an easily digested manner

THE CONSUMER

Needs to be provided with: • an exploratory

capability • a versatile set of tools • a versatile set of

visualizations •  training/education

THE EXPLORER

Two Distinct Modes

There are two distinct modes of information usage:

u  REAL-TIME/BUSINESS-TIME: Information is a contributor to another activity

u  CONTEMPLATIVE ANALYSIS: •  Information is a material to work with and

analyze •  Visualization contributes to this analysis •  Just as there are statistical algorithms, there

are visual algorithms

NOTE THAT ANIMATION ADDS A DIMENSION. WE CAN SEE THINGS VIA ANIMATION THAT WOULD

OTHERWISE BE INVISIBLE.

The Burning Question

WHICH data visualizations are the most effective

for WHAT?

u  What does IBM know about the effectiveness of any specific visualization and how do we know it? How is it measured?

u  Is there a relationship between visualization and data volumes? If so, what is it?

u  Are some people poor at deriving meaning from visualization – and yet skilled in other ways?

u  What is the learning dimension and how is it characterized?

u  What does IBM know about animation and cognition, if anything?

u  You suggest that there are best practices. How do we know – what research has been done? Are there cultural variances?

u  Are there visualizations that are yet to be discovered?
