This is an amazing video. It starts out a bit slow, but it's worth watching. The video's from the TED website (the same people who gave us the Ken Robinson video).
"You've never seen data presented like this. With the drama and urgency of a sportscaster, Hans Rosling debunks myths about the so-called "developing world" using extraordinary animation software developed by his Gapminder Foundation. The Trendalyzer software (recently acquired by Google) turns complex global trends into lively animations, making decades of data pop. Asian countries, as colorful bubbles, float across the grid -- toward better national health and wealth. Animated bell curves representing national income distribution squish and flatten. In Rosling's hands, global trends -- life expectancy, child mortality, poverty rates -- become clear, intuitive and even playful."
