Class JGraphRadialTreeLayout

java.lang.Object
com.jgraph.layout.tree.JGraphRadialTreeLayout
All Implemented Interfaces:
JGraphLayout
public class JGraphRadialTreeLayout extends Object implements JGraphLayout
Lays out the nodes in a graph as a radial tree (root at the centre, children in concentric ovals).
