Recently, more thorough taxonomies by Nusrat and Kobourov, Markowska, and others have built on this basic framework in an attempt to capture the variety in approaches that have been proposed and in the appearances of the results. Thus, the original shape is completely eliminated, and contiguity may be retained in a limited form or not at all. Are . In the case of cartograms, by scaling features to have a size proportional to a variable other than their actual size, the danger is that the features will be distorted to the degree that they are no longer recognizable to map readers, making them less useful. While an area cartogram manipulates the area of a polygon feature, a linear cartogram manipulates linear distance on a line feature.

I gave a talk, long long ago, about some of these map varieties. size, shape, orientation, and contiguity. This connectivity is called topology.

Physical or topographical maps show relative area, distance, and terrain, but they do not provide any data about the inhabitants of a place. A cartogram is called a thematic map in which a mapping variable such as travel time, population, or GNP is substituted for land area or distance. Finally, a couple of outliers.
