public class JGraphLayoutExample
extends GraphEdX

An example applet that provides features for testing the JGraph Layout package. Sample data can be inserted, the layouts applied, cells moved while the layout auto-applied and morphs the cells into position. This example also supports grouping and expand/collapse.
