Area cartogram maps are maps of non-absolute space where the areal extent is in proportion to some measured value.

Area cartograms are useful for visualizing relativity based on a common quantitative attribute such as population. Cartograms were popularized by Erwin Raisz who published the first statistical cartograms of the United States . Area Cartogram Maps Explored
