Explanation

A cartogram turns a map into a graphic representation of facts and numbers associated with different countries or regions. As an example, to dramatically show which countries on a continent have the largest populations, a cartogram might distort the relative sizes of each country. Those with larger populations are made to appear larger in comparison to those with smaller populations — despite their actual relative sizes. In this way, the map is changed into a picture that conveys specific information about the places, showing different populations as the sizes of the countries. Cartograms may have odd-looking shapes and dimensions, but they can be a good way to show important information.
