Imbalance: Guardian 2010 Election Graphics

For the Imbalance brief I will be looking at infographics. I would like to be creating something as clean as the Guardian's graphics for this year's election. Very crisp, simple and well designed.

See them in there interactive forms on Guardian's website here: http://www.guardian.co.uk/politics/interactive/2010/may/06/uk-election-results-map
