This has consequences as the map attempts to balance statistical accuracy, geographical accuracy and topological accuracy. For graduated images or corresponding images, it's anything but difficult to assess esteem dependent on the size of the image. Maps depend on variation in scale to represent a large area and a cartogram is not a true representation of the real-world area and may give incomplete information.

Both area and linear cartograms adjust the base geometry of the map, but neither has any requirements for how each feature is symbolized. The variety of approaches that have been proposed include cellular automata, quadtree partitions, cartographic generalization, medial axes, spring-like forces, and simulations of inflation and deflation. Develops clarity in a map that otherwise might be cluttered with unnecessary information. Cartograms leverage the fact that size is the most intuitive visual variable for representing a total amount. Cartograms visualize the concentration of data in a boundary by distorting its shape and size relative to other geographic areas on a map.
