If you are a visual learner like me, or you just happen to like nifty animated maps, a site called SHOW World may be worth spending an afternoon coffee/tea break or two to check out. Similar to the popular WorldMapper collection, this site displays a lot of data from a number of sources (including, apparently, the World Bank) in map form. On an Excel spreadsheet, the information would just look like numbers or a boring old graph. But this site, as SHOW World puts it, offers "a new way to look at the world by resizing countries on the map according to a series of global issues."
The site appears to be adding new datasets to compare, but as it stands you can compare countries on everything from urban populations and CO2 emissions to even Internet usage.
The embedded map below enlarges countries with higher gross domestic product, shrinking those with smaller GDP. Click the center of the map to resize it (or check it out here).
