public class NestedTutorial
extends java.lang.Object

This example shows three alternatives to display a prepopulated graph model in a window. Prepopulated means that there are already nodes in the model before the model was placed in a GraphPane. There was a problem in the initial release which made this break. That problem has been fixed and it will just work now, except for one little gotcha, which is if you set the model while the window is closed, the GraphPane thinks its size is 0x0, so the nodes all get layed out in the upper-left corner of the canvas. The way to fix this is to either set the model once the window is open, or explicitly call a global layout once the window has been opened. More comments below in the individual methods.

In this version you construct the graph widget with the model, and apply a layout to the graph once the window is showing. I think the "set model post display" version is preferable, but this might be useful in some cases.
