GDP (PPP) per capita and life expectancy: Gapminder

I've found the definitive graph of GDP (PPP) per capita vs life expectancy at gapminder.org. It's better than mine because you can see the same data over time (since 1950) and dots are colored to correlate to parts of the world. And you can play around with it. By selecting particular countries, it will highlight their paths over time. Sort of hard to describe. For example, if you chart simply GDP over time, and you select Luxembourg and the US, you'll see that our GDPs matched and grew together until 1988 when Luxembourg's took off.
