The Bill and Melinda Gates Foundation has a nice little “Infographics” section on their website, showing statistics of diseases like Polio around the world. They have some nice charts, graphs, and timelines on their site, along with some rather suspect ones. FlowingData points out one particularly bad example of lumping causality and correlation together.
(…) there’s one graph that I gave a double take. It shows the correlation between IQ and disease burden. Question of the day: if we decrease disease burden in a country by improving healthcare (or availability of vaccines), will the country as a whole become smarter, or are better educated people generally healthier?
