1Oliveros, J.C. (2007) VENNY. An interactive tool for comparing lists with Venn Diagrams. http://bioinfogp.cnb.csic.es/tools/venny/index.html
This tool is an online venn diagram generator. The venn diagram is calculated through javascript and therefore, no data is send to the server. Only the proportionally scaled diagram comes from Google's image generator, so information about the relative group sizes is send to Google's servers. Feel free to use and modify the source of this page as you like.
