Here it is! Live on Google. Gapminder is the Trendalyzer software used by Hans Rosling and acquired by Google. It's now online at Google, but it looks like an early test. I'm not sure if you can use your own data yet or not, but that is one of the goals.

Check out all of the Gapminder tools, and see more presentations using the Gapminder software at www.gapminder.org
