Below are a couple of old but fun data visualization related presentations from Ted Talk
Hans Rosling (the entertaining Swede in the second video) created Gapminder to animate his data ever so effectively. The software behind Gapminder; Trendalizer, was acquired by Google and is currently only used by Google Labs.
From an animation perspective, the software appears to make complex animations and transitions appear quite easy. Hopefully soon, they will be incorporating some of these features into Fusion as well.
The video effect of the Trendalizer approach also made me think of Steve Varga who is doing some cool things with interactive data vis on the iPad. He will be coming to talk to us later this term on a variety of his experiences.
