Graphviz

Recently I have just completed making a relationship graph for VoidNet. It was a task that I didn't think would be that easy. However I was delighted to discover that there is a tool capable of drawing relationship graphs automagically. Just when you thought that opensource didn't have an answer for everything, along comes yet another fantasic tool.

Graphviz is extremely simple to use, I was able to cobble together the graph that I wanted with nothing more than a few lines of input. Let me give you a quick example of a really simple graph.

 echo 'graph G { a -- b; }' | dot -Tpng -o graphviz01.png

This produces a simple graph linking a and b.

You can do much more linkages than just two of course, for instance:

Take a look at my VoidNet Map and why not look at the GeoMap I did at the same time. I will be producing a howto soon!
