Although with most Venn diagrams, the enclosing shapes are generally circles, they don't need to be the same shapes, and you can have Venn diagrams with more than three sets. Some examples here: http://en.wikipedia.org/wiki/Venn_diagram Also, a Venn diagram technically is a subset of the more general Euler diagram. The Venn diagram illustrates regions for all possible combinations of intersections, e.g., for three sets ABC, A-only, B-only, C-only, A+B only, A+C only, B+C only and A+B+C. A Euler diagram can be used where, for example, A intersects B but not C. More info at http://en.wikipedia.org/wiki/Euler_diagram I note the External Links section on the Venn diagram lists links to several tools to create Venn diagrams. I don't know if any of them are python, but if the OP is not limited to python-only solutions, they may help. _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
