You can link two entities and store a name-entity "Map" for the link. That is you dont store more than one link for a pair of nodes but rather as you discover other relations(links, attributes whatever you are calling them) you just add that to the map object you have for the link. I have used JUNG (java universal network and graph library) before, and it was pretty easy to do these mouse events and so. The only thing is, it's a library and written in Java.

Hi,
Maybe this is an old topic but I can't find related answers.
I have some data containing certain "entities" related to others by one or more attributes. For example, Alice's cat may be connected to Bob's dog because both are named "Bill". Also, they can be connected because they live in the same county. Furthermore, Bob's dog can be connected to Chuck's bird because they are of the same color
Something like this:
(A'sC)--------------(B'sD)-----------------(C'sB) Name=Bill Color=Beige County=CD
The issue is, the attributes connecting entities can be hundreds or even thousands, so creating a graphviz file showing all those connecting attributes in the edges will result in a mess. Instead, I would like to create an application such that only the vertices (with a label inside) and the edges (without nothing) are initially shown, and when the user double clicks on a specific edge then some window can appear showing all the attributes causing X and Y to be connected in the graph.
I know I can create the graphs using BGL, but once I have the graphs I do not know what library to use in order to visualize it
Can somebody help? Perhaps there is a different/better way of doing the same with a different tool like GraphML + Some Visualization program?
Thanks,
Mark
