Funny you should ask about graph tools. I've just been using the Directed Acyclic Graph Browser which comes on a tools disk (#3) for Smalltalk V. It does a lot of what you want, e.g. maintaining links when you move a node, redrawing the graph (when asked), after you have changed the structure. I'm using it to write a conceptual graph editor. It's not PD ($99 for Smalltalk, maybe $50 for the tools disk), but then you get a whole programming language and prototyping environment with it!
