Political Landscapes of London at Views of the World (hat tip):
In my analysis of the 2008 election (data was kindly provided by Michael Thrasher of the University of Plymouth), I took a look beyond the two main parties and mapped the proportional distribution of votes for all political parties that had a candidate standing for election at the 2008 mayoral election. The geographical patterns that emerge are expression of the diverse demographics that compose the social landscape of the capital. In the map, each party’s individual shares are mapped onto a gridded population cartogram of London.
It is important to keep in mind that each of these patterns stands for considerably different total votes.
