Yes, JGraph has these capabilities (in the addons package), so if you
use the JGraphModelAdapter to make JGraph and JGraphT work together, you
can auto-layout your visualization. Here's some example code (assuming
you already have the model, view, and adapter tied together):
void layout(
ListenableDirectedGraph graphModel,
JGraphModelAdapter graphAdapter,
JGraph graph)
{
List roots = new ArrayList();
Iterator vertexIter = graphModel.vertexSet().iterator();
while (vertexIter.hasNext()) {
Object vertex = vertexIter.next();
if (graphModel.inDegreeOf(vertex) == 0) {
roots.add(graphAdapter.getVertexCell(vertex));
}
}
JGraphLayoutAlgorithm layout = new SugiyamaLayoutAlgorithm();
layout.applyLayout(graph, layout, roots.toArray(), null);
}
