became a computer geek who studied contemporary dance.

data visualization isa particular way of doing

information design

“ Information design tells a story with pictures.

It can tell “how many?” “when?” or “where?”

It can show trends over time, compare elements or reveal hidden patterns.

It brings form and structure to information.

It is not the same as graphic design, nor is it only about making something aesthetically pleasing.

It is not about branding, style, making a glossy product or something that looks “corporate.”

“ Clear

It makes complex information easier to understand.

Compelling

Visuals grab people’s attention.

Convincing

People who might not be persuaded by raw numbers or statistics may be more likely to understand and believe what they see in a chart or graphic.

Powerful interests are connected through complex networks of influence that significantly affect US public policy

around climate change.

Users can construct their own maps by placing, removing, and rearranging institutions and individuals associated with claims that anthropogenic climate change is not a cause for concern. The interface allows users to explore for themselves relationships between the petroleum industry, various think tanks, and the US government.

Visualizing data is not an unproblematic activity.

Methods used

IN GENERATING AND COLLECTING DATA,

IN CHOOSING APPROPRIATE VISUAL ELEMENTS,

OR IN DISSEMINATING A VISUALIZATION

can be subject to debate.

● Data visualization assumes the presence of data● Broad strokes might miss important details (which

is why interactivity is important)● All the visual cleverness might eventually become

tiring. (“I'm skeptical of shapes.”)

But work in data visualization can be an interdisciplinary activity, where experts

IN DESIGN,

IN EDUCATION,

IN SOCIAL SCIENCE,

AND IN TECHNOLOGY

contribute best practices in the spirit of free inquiry, openness, and trust.

Visualizing data is not an unproblematic activity.

But that's OK.

When you want to say something radically different, or when you uncover information that is potentially dangerous to the status quo,

say what you want to say in the most aesthetically stunning, quantitatively sound way possible.

1) Join the Information Design for Social Change email list.groups.google.com/group/disenyo

2) Try it yourself. Graph your social network on Facebook on www.nexus.ludios.net. Or try out Many Eyes: www.manyeyes.alphaworks.ibm.com/manyeyes

3) Read up more about it on the Web: www.delicious.com/dmaranan/visualization

4) Read books and journal articles about data visualization:wednesdaysmnlove.blogspot.com/2008/10/list-of-readings.html

5) Go to a school that teaches you more about it.Look for buzzwords like Aesthetic Technologies, Computational Aesthetics, Computational Design, Information Design
