Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest.
Interesting to see, among many maps, the science research maps, where publications by United States were more than three times as many as those published by the second highest-publishing population, Japan. The science growth map is also interesting for us editors, showing the growth in scientific research: if there was no increase in scientific publications that territory has no area on the map.
There are 366 maps, also available as PDF posters.
