Most of the available cartogram generation tools work in conjunction with other GIS software tools as add-ons or independently produce cartographic outputs from GIS data formatted to work with commonly used GIS products. As with map projections, the tradeoffs inherent in cartograms have led to a wide variety of strategies, including manual methods and dozens of computer algorithms that produce very different results from the same source data. use simple symbols. The various strategies and algorithms have been classified a number of ways, generally according to their strategies with respect to preserving shape and topology. Do not use data derived by area like population density. However, one of the first cartographers to generate cartograms with the aid of computer visualization was Waldo Tobler of UC Santa Barbara in the 1960s.

Schematic maps based on quadtrees can be seen as non-shape-preserving cartograms when some degree of neighborhood preservation might be needed. Once constructed, cartograms are often used as a base for other thematic mapping techniques to visualize additional variables, such as choropleth mapping. [18] Some attempt to preserve some semblance of the original shape (and may thus be termed homomorphic),[25] but these are often more complex and slower algorithms than those that severely distort shape. The goal of designing a cartogram or a map projection is therefore to represent one or more aspects of geographic phenomena as accurately as possible, while minimizing the collateral damage of distortion in other aspects. Many maps when put together make an atlas and show various continents, countries and can provide information about any particular aspect. In either method, a careful examination of the logic behind the use of the cartogram must first be undertaken."
