weka.gui.treevisualizer.TreeVisualizer
Class for displaying a Node structure in Swing.
To work this class simply create an instance of it.

Resize it to the desired size.
When using the Displayer hold the left mouse button to drag the tree around.
Click the left mouse button with ctrl to shrink the size of the tree by half.
Click and drag with the left mouse button and shift to draw a box, when the left mouse button is released the contents of the box will be magnified to fill the screen.
