Thought I would see what the Advogato trust web looked like
with graphviz. I would not recommend anyone else doing
this, as it takes longer than I wanted to wait. Running it
on just the purple lines finished in reasonable time, but
ghostview was not usable with such a large single page PS
Someone suggested adding support for graphviz. As
graphviz is not open source (despite what they say they
believe in their licence faq), we can’t link it with dia.
If I get around to doing this, it would probably involve
modifying graphviz to export the data in an easily readable
format, and getting the import filter to read this data
through a pipe.
