JGraphT includes a full distribution of JGraph, and by running 
JGraphAdapterDemo, you are already using JGraph. As the class name 
indicates, this is only meant as a demo; if you want to do anything 
serious with JGraph, you have to dig deeper into their API.

For example, JGraphModelAdapter.JGraphListener handles events from 
JGraph and translates them into corresponding modifications to the 
JGraphT model, but it doesn't do anything with selection events. For 
those, you would probably need to start here:
