GapMinder is an online time-waster (that might sometimes be considered a useful tool) that helps visualize many different statistics from different countries into a single neat graph. In this photo, I'm comparing the Sulfur emissions per person (y axis) to the % of self-employment (x axis) to CO2 emissions (size of bubble) in different countries. It's cool to mess around with, especially the effect of time on the numbers (you can scroll through the years to compare).
