JGraphT visualization using JGraph

http://www.jgrapht.org/visualizations.html

The following applet shows how a JGraphT graph can be visualized using JGraph. Try to play and drag around thevertices and edges to get the feel of it.
Note: Java 1.3 or above must be installed for this applet to work correctly.

a JGraphT graph visualized using JGraph.

It's very simple: the JGraphT librarycomes with an adapter that makes JGraphT graphs compatible with JGraph. To visualize a JGraphT graph you just need to initialize JGraph via that adapter. Example code:
// create a JGraphT graphListenableGraph g = new ListenableDirectedGraph( DefaultEdge.class );

// create avisualization using JGraph, via the adapter JGraph jgraph = new JGraph( new JGraphModelAdapter( g ) );

Is that all?! Yes, that's all. Any modification now made to the graph g will automatically bereflected by the JGraph component.
