ActionData Visualization

“If no one remembers the numbers then you have not communicated”

– Robert Kosara

“Visualization doesn’t happen on a page or on a screen.

It happens in the viewer’s brain” – Robert Spence

“By visualizing information, we turn it into…a sort of information map. And when you’r

e lost in information, an information map is kind of useful.” – David McCandless

“More often than not, the presentation of quantitative information fails to

communicate information clearly and efficiently” – Stephen Few

“Fundamentally, Data Visualization is not about technology but about Que

stions and Answers” – Jeff Heer

“Most dashboards…deliver only a fraction of the insight that is nee

ded to monitor the business.” – Stephen Few

What do the scientist say?

"More than ever, research is highlighting a trend in reduced attention and

concentration spans…the younger generation appear to be the worst

afflicted," - sociologist David Moxon

“…individuals who multitask emails, phone calls and social-networking sites

have more trouble paying attention and focusing on important information” –

The New York Times

“…lack of attention has a serious impact on task performance and increases

the risk of accidents.” – sociologist David Moxon

Stress and Attention Span

“When you are stressed … this stress takes a lot of resources

from your brain and interferes with your capacity to encode any

new information.”
