[OS X TeX] Program to draw Venn diagrams?

[Joseph C. Slater]

The metapost method listed above is very simple.
For stolen exampe:
Create a metapost file vennfigure.mp with contents:
input venn;
beginfig(1);
  draw_venn_three(false,false,true,false,true,false,false,false);
  draw_venn_three(false,true,false,true,false,false,false,false)
  shifted (4cm,0) withcolor white;
endfig;
end

Download venn.mp (from the link posted by Jean-Claude)

mptopdf vennfigure.mp

You will have a vennfigure-0.pdf file the looks so nice.

Alternatively, you can just put the metapost code in your latex 
document (much faster), but I'll let you look up how to do that.
