Class CirclemapDraw

java.lang.Object
  ch.randelshofer.tree.circlemap.CirclemapDraw

public class CirclemapDraw
extends java.lang.Object

CirclemapDraw draws a CirclemapTree.

Can draw a subtree from any node within the tree.

Author:

Werner Randelshofer @version 1.2 2009-02-04 If we prune on the depth of the tree, fill the composite node only by an amount which visualizes its weight.
1.1 2009-01-30 Added maxDepth property.
1.0 Jan 16, 2008 Created.
