Via ScienceBlogs, Google’s Gapminder provides an interesting way to visualize statistics about wealth, life expectancies, pollution, with trends over time.
Some of the results are counter-intuitive, and sometimes you have to pay close attention to what is being mapped — for example, economic growth in the United States isn’t a steadily expanding circle, but a slowly-pulsing one, because the animated chart is tracking the rate of growth each individual year.
The Gapminder requires some effort and attention, but it’s worth exploring.
