Hah! My horrible (truly, truly horrible) code. I mean, the graph output was nice compared to what it replaced, but when I went to rewrite it later (a project that never got fully released, oh well) I wanted to go back in time and back-handed slap myself in the face.

P.S. I am a little annoyed that the list could be interpreted as meaning I am not "first author" when in fact I wrote pretty much literally all the code, and was the one who had the idea for the whole project in the first place. Oh well. :-)
