Thanks again.  I found those examples just after I wrote so I apologize for jumping \
the gun.  I followed the examples and got the JFrame and the Panel showing up just \
fine but there is no graph in the panel.   I just get the background image. I have \
tried the various ways that I have seen from the various examples \
(vtkRenderWindowPanel directly inside a JFrame,  vtkRenderWindowPanel inside a \
JPanel, which is inside a JFrame) but I still only get a background image.  The only \
difference I can see is that for this early test I did not create a class that \
extends JFrame. I just instantiated a JFrame directly in my main program.  I also \
only have one panel, neither of which should make a difference (I would think.)

My JFrame also refuses to close when the red X is clicked which I also don't \
understand but am ignoring assuming it is related to the fact I can't see my \
tree/graph. 

Any help pointing out my problem would be greatly appreciated.

Code below

//snip
Input to graphView is the output from GroupLeafVertices and worked just fine when \
displaying a vtkGraphLayoutView directly

		vtkGraphLayoutView graphView = new vtkGraphLayoutView();
		graphView.AddRepresentationFromInputConnection(vertices1.GetOutputPort()); 
		vtkRenderWindowPanel panel = new vtkRenderWindowPanel(graphView.GetRenderWindow());
		// configure the graphView	
		graphView.SetVertexLabelArrayName("Destination");
		graphView.SetEdgeLabelArrayName("Session Count");
		graphView.SetVertexLabelFontSize(14);
		graphView.VertexLabelVisibilityOn();
		graphView.SetEdgeLabelVisibility(true); 
		graphView.SetLayoutStrategyToCommunity2D();
		graphView.SetEdgeColorArrayName("Session Count"); 
		graphView.ColorEdgesOn(); 	
		graphView.ResetCamera();

		// set the size and background of the vtkRenderWindowPanel
		panel.setSize(600,600);
		panel.GetRenderer().SetBackground(0.8,0.8,0.8); 
		// get the JFrame
		final JFrame frame = new JFrame();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

		// set up in the interior JPanel
		JPanel mainPanel = new JPanel(); 
		mainPanel.setSize(600,600); 
		mainPanel.setBackground(Color.white);
		mainPanel.add(panel); 
		mainPanel.setVisible(true);

		frame.getContentPane().add("Center", mainPanel); 
		frame.setTitle("Test Tree"); 
		frame.getContentPane().setVisible(true);
		graphView.Update();
		panel.Render();
		graphView.ResetCamera(); 
	 	graphView.Render();
		frame.pack();
		frame.setVisible(true); 

		frame.addWindowListener(new WindowAdapter() {
		      @Override
		      public void windowClosing(WindowEvent e) {
		        // Calling vtkGlobalJavaHash.DeleteAll() will clean up
		        // VTK references before the Java program exits.
		        vtkGlobalJavaHash.DeleteAll();
		        frame.dispose(); 
		        System.exit(0); 
		      }
		    });
}

//end snip....

Take a look at the examples in

VTK-git/Examples/Infovis/Java
