I suggest that world maps with countries colored by some statistical feature often would be more useful if done on a cartogram that is a compromise between population and size of countries, rather than on a map with a simple Mercator projection. The problem of Earth’s curvature mentioned in the article would not seem to be an overwhelming obstacle. It is interesting that the electoral college presidential-voting system in the United States appears to amount to a rather good compromise between the relative importance of a region’s population, or number of voters, and its size.
