Hello Xperts,

a friend of mine asked me the following questions: (any suggestion?)

"Is there a commercial tool to create a custom graph editor that let
the user interactively draw a graph where each node is represented by
a named graphic icon connected to other icons by line segments?

More precisely, we would like:
- to define a small library of icons corresponding to object classes
- let the user create instances of icons with arbitrary names
- let the user create, save, load and edit a graph
- let a program access a data structure representing the connections 
between objects
- let a program dynamically choose another icon for a node (to highlight
a node for instance)

Thanks for your help.

Francois."

Thanks for him.
