I spent a bit of time on twitter. I found the following:

"A recent survey on CGarchitect.com found that almost 90% of respondents were more likely to win a competitive bid using visualizations. More than 90% said community support was easier to win with visualizations. And 50% said they saved nearly $25,000 a year by creating visualizations in-house." http://m.readwriteweb.com/archives/how_visualization_is_changing_design.php

Nice pictures, but not really interesting: http://www.nytimes.com/interactive/2011/05/15/magazine/art-of-economic-compl...
