I have four sets of IDs (stored in separate text files) and I would like to create a Venn diagram showing how these sets overlap. I was able to paste the lists into this web app and get a simple diagram, but I'm looking for something over which I have a bit more control (colors, graphic size, etc). Any suggestions? My first thought would be R, but I'm comfortable trying anything out.

So, in the provided app you are just painting text on top of a fixed image, right? And you want to be able to create Venn-diagrams with four sets with your own colors? In that case you should be fine with pretty much any server side scripting language, i.e. PHP or ASPX. If your solution is fixed to four sets (or less), placing the ellipses appropriately should be simple math. ImageMagick should i.e. do the trick in many community-developed programming languages.
