When is a map not a map?

This map shows countries of the world, not by their actual size and shape, but distorted to show the ones which have seen the biggest economic growth.
This is one example of how maps can be used to show information in eye catching and challenging ways. But remember, all maps distort reality, because it is impossible to accurately depict a curved surface on to a flat page
