Draw an area-proportional Venn diagram of 2 or 3 circles

The draw_venn function creates an area-proportional Venn diagram of 2 or 3 circles, based on lists of (biological) identifiers. It requires three parameters: input lists X, Y and Z. For a 2-circle Venn diagram, one of these lists should be left empty. Duplicate identifiers are removed automatically, and a mapping from Entrez and/or Affymetrix to Ensembl IDs is available. BioVenn is case-sensitive. In SVG mode, text and numbers can be dragged and dropped.
