These charts from DataVisualization.org show art sales for 270 of the top works sold during 2008-2011. The charts are fun to play with. It’s only a shame that the sample could not have been larger than 70 or so works per year. Each bubble represents a work of art, the size indicates the value, the color the type of work (red for silk screens, blue for sculpture, orange for paintings, white for drawings.) Click through to play with the charts and see which works each bubble represents.
