+
+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
