Other cartogram software

A user-friendly JAVA program implementing our cartogram method called ScapeToad has been developed by programmers at the Choros Laboratory in Lausanne. You can find it here. There is also an (unrelated) on-line JAVA version of our method created by Frank Hardisty, which you can find here, and there are free cartogram add-ons for ArcGIS and MapInfo. There is an R version of the code given here called RCartogram, which you can find here.
