Plotting tools for networks, part I

After dicking around with GraphViz in college, I finally realized its power (and the power of the Dot language) when I discovered the "gvpr" tool, which is basically AWK for graphs.

If Graphviz's layouters don't do what you want, you can try writing a GVPR script to do so. The really powerful thing is that you can process your initial Dot source via a pipeline of GVPR (or other!) scripts that augment the layout (by adding to dot source), then pass that into a layouter which will preserve your parameters. Check "man gvpr".
