A cartogram is a map in which a mapping variable – such as travel time is substituted for land area. The geometry or space of the map is distorted in order to convey the information of this alternate variable. There are two main types of cartograms: area and distance cartograms. The map above would be a area cartogram as it displays diversity of amphibians throughout different countries.
