Hans Rosling’s profile on TED:
Go straight to Gapminder.
About Gapminder: The initial activity was to continue development of the Trendalyzer software. This software unveils the beauty of statistical time series by converting boring numbers into enjoyable, animated and interactive graphics. The current version of Trendalyzer is available since March 2006 as Gapminder World, a web-service displaying time series of development statistics for all countries.
Statistics can be enjoyable? You really have to see it to believe it.
