ScapeToad cross-platform, open-source cartogram software

The scapetoad dev team has informed me about an interesting cartogram software. ScapeToad is a cross-platform, open-source application written in Java, using the ESRI Shapefile format for input and output. It also exports maps in SVG format and is provided with a cartogram creation wizard which guides the user throughout the map creation process. See http://chorogram.choros.ch
