Data doesn't have to be boring. Above is a collection of images from Visual Complexity with links to 460 projects. Also, Mashable has a nice review of 16 data visualization tools (some of which I hadn't see before). You may have seen Hans Roslings speech at the TED conference where he enthusiastically demonstrated Gapminder’s Trendalyzer software. Google recently bought Trendalyzer and has a live test site here (it's fun to play with). Of course Swivel is cool too.
