pyvenny v0.1-alpha

Plot four set venn diagrams, like venny (http://bioinfogp.cnb.csic.es/tools/venny/) but using python sets:

I just drew the damn thing using inkscape and then used that as a jinja template. Set algebra I just did by hand.

To use:

>>> import pyvenny
>>> with open('diagram.svg', 'w') as f:
         f.write( pyvenny.render_four_set_venn(
         set(['a','b','c','d']),
         set(['b','c','d','e']),
         set(['c','d','e','f']),
         set(['d','e','f','g']))
