It is in the planning to rewrite Graph on top of PTCPas. I hope to do this 
before 2.2 it released. In the meantime ggigraph might suit your needs.

Implementing graph on top of SDL might also be an idea, but it should then 
be built on top of JEDI-SDL, and reuse the existing graph 
code. Implementing graph in C seems like a bad idea to me.
