Apparently I didn't correctly subscribe to this thread, sorry for the delay.
I created it with perl, bash, a mysql server, and a package called graphviz. Feel free to link, use, and generally do whatever you want with it. There's plenty of room for improvement, I was just in the mood to automate something. I threw it all in a little github repo so it's easy to distribute:

(I tried putting it in quote tags instead of url tags and it still broke the links). Let me know if you run into trouble, assuming I get the email set up right this time.
