Political cartograms

I just found (finally a web version after 2 hours struggling to find on the web) an interesting map of the political geography of Switzerland. It depicts last week-end' votation. Swiss people had to vote for the integration of their country in the Schengen/Dublin zone. Here is a map done by Jacques Levy (at epfl). It depicts the proportion of votes according to the density of population: There seems to be a clear distinction between cities and countrysides. The source of this picture is this document (published by swiss newspaper Le Temps). Thank you <a href="http://www.timtom.ch/blog/index.php"TimTom for the colored version!
