The program you need in order to deal with a dot file is Graphviz. It is cool! Why?
1. One can specify an entire pretty vector-graph in a text file. 1a. The two main wikis that I use, PmWiki and IkiWiki have plugins for graphviz, which means one can add graphs to web-pages just by editing them.
2. One can write scripts to generate dot files for you (as firefoxy has already demonstrated) 2a. I wrote a script to help me sort out assignments for the Multi-Fandom Lyric Wheel ficathon by giving me a graph which showed the fandom match-ups between fandoms that participants could write and the ones that recipients wanted to receive. It made it a lot easier.
