Project Summary

Perl extension for generating cartograms, maps in which the sizes of the enumeration units have been rescaled according to an attribute they posses rather than their actual size.

Resizing a map's regions in a way that keeps the map recognizable is a difficult problem. Michael Gastner proposed a method and made available a C program to generate cartograms. By now, Geo::Cartogram simply takes a map in ESRI's shapefile format (.shp) and a user-defined function to generate the files needed for Gastner's program to run.
