In this video, Hans Rosling demonstrates GapMinder, a tool for “unveiling the beauty of statistics”. The content for the brief video is the change in the life expectancy & income throughout the world in the last two centuries. Gapminder looks like a really neat tool, and the trends described through the tool are interesting.
