public class VisualGraph

extends java.lang.Object

Title : VisualGraph

Description : VisualGraph is a visual wrapper for Graph: a VisualGraph contains a reference to a Graph with visual attributes and methods. In this way, visualization (or drawing) of a Graph is separeted from the structure Graph.
