.. class:: infomark

This is a wrapper for R package VennDiagram. It allows you to plot two-set or three-set venn diagrams based on counts. The R script used to generate the plot is also in the output. 

Input: labels for sets and counts for each region in the diagram.

A: A-only

B: B-only

C: C-only

AB: in A and B but not C

BC: in B and C but not A

AC: in A and C but not B

ABC: in A, B, and C 

-----

**Example**

Labels: X,Y

Counts: 30,10,20


.. image:: ./static/images/venn2.png


Labels: A,B,C

Counts: 10,20,30,40,50,60,70
