Venn Diagrams

I'm looking for a graphing program that handles Venn Diagrams exceptionally well. I would like to have diagrams built where the set sizes and overlap sizes are properly set based upon the data. Most Venn Diagrams I see have uniform circle and overlap sizes which of course do not properly convey the data.

New book on Venn diagrams, very favorable review in Nature (22 July 2004):

A.W.F.Edwards, Cogwheels of the mind: the story of Venn diagrams (2004)

-- Edward Tufte

Here's what you were looking for, perhaps. You just have to download and unzip it . The .exe file is a simple program that produces a quantitative Venn. It only has room for two sets unfortunately, but it's still very useful.

Dear Todd,
