The Winter Olympics in Vancouver yielded some great visualizations, with the New York Times work being amongst the top ones. They are showing off a map of the Winter Olympic Medals in the tradition of the Dorling cartograms. They also did a great job on a 3D map of the venues.
For those who want for worldmapper style maps, here is the relief: The worldmapper map of the actual medal count. The following is transformed due to a country’s total number of medals it has won.

A larger version of the map can be viewed by clicking on the image.

Splitting the results in Gold/Silver/Bronze shows that the general trend remains, making the Olympics a quite one-sided competition between the wealthy countries (and China), no matter whether it is the first, second or third rank in the results tables:

    This is a short slideshow showing the basic steps that are needed to do your own gridded population cartograms (with a quite rough 1 degree grid – good for starting with this whole thing). Software needed for this simple click-through tutorial are ArcGIS and ScapeToad. If you want to go one step further, I’d recommend using the ArcScript Cartogram Geoprocessing Tool by Tom Gross, even though this is not featured in this demonstration:
    The demonstration was given in October 2009 for students of the Module GEO6016 Data, Visualisation and GIS in the MSc in Social and Spatial Inequalities at the University of Sheffield.
