For some reason I have to draw a lot of venn diagrams and I hope I can just specify the sets and its elements and it emits the right image. I do not care about the blazonry.

So is there any tool or script or libraries suitable?

pyVenn is a python library that shoud help you: http://code.google.com/p/pyvenn/

an alternative would be matplotlib-venn, which the author describes here. It supports multiple sets, but depends on matplotlib.

    It seems that pyVenn can only support two sets:-( Dec 17, 2012 at 10:42
  • then use matplotlib-venn, which depends on matplotlib Dec 17, 2012 at 19:00

Excel includes this functionality. Microsoft's documentation for creating Venn diagrams is found here: http://office.microsoft.com/en-us/excel-help/create-a-venn-diagram-HA010335959.aspx

There are a few relevant options:

Lucidchart has a Venn diagram maker. It provides a lot of flexibility but the tradeoff there is that it requires a bit more manual effort to get it sorted correctly.

matplotlib-venn is a Python package that is more scripted.

I use the venn diagram template from Lucidchart to draw mine. It is super easy to use and integrates with google drive.

This one is good for generating 2 or 3 sets, from real data http://simbioinf.com/mcbc/applications/genevenn/genevenn.htm
