I have already seen maps using deformation to visualize information. For example, this map shows temporal distance between some French cities when traveling by train: http://www.nf-ameublement-pro.com/sc/images/new/newsletter/septembre/carte_france.jpg

Is there a name for this kind of maps? Also, is this type of map available in some GIS softwares?
