Your ideas looks most promising. I'll look at your code more fully when I get a moment.
I'm impressed how easy it is to knock up some simple and small encodings of graphs using SVG. You may be amused at my quick
I am now convinced that the basic idea of using SVG for this sort of job is right. The file size is 3 kb and that is in a fairly
verbose style and includes comments - it could probably be nearly halved with more care.
Good luck with your GSoC application.
PS I'd be interested to know which browsers can display the attached file - Adobe SVG viewer is needed for IE6 at least.
