David McCandless has captured more than a little of the wonderful diversity you can find around the world in this map of International Number Ones. It has some thought provoking juxtapositions. The U.S., for example, is #1 for serial killers while Cuba is #1 for doctors.
The map is also interactive in that if you move the cursor over it, the names of the countries show up. This feature is especially fascinating when looking at unfamiliar parts of the world.
