Just a personal point of view: I usually end up implementing custom graphs or 
trees because it is rather simple [*] and because of the variety of structures 
and features. (Maybe that's why there are no general purpose node/tree/graph 
libs, only highly specialised one, as for XML parsing.)

If you take this route and need help or advice on given points or features, we 
can probably be of some use.

[*] compared the overall app: if a graph is complex, then the app it is a 
component of is even more complex
