Class Radial

java.lang.Object
  edu.uci.ics.jung.visualization.AbstractLayout
      com.hp.hpl.guess.layout.Radial

All Implemented Interfaces:

ChangeEventSupport, Layout, VertexLocationFunction

public class Radial

extends AbstractLayout

The layout computePositions method follows the algorithm as given by Eades in his paper "Drawing Free Trees", Bulletin of the Institute for Combinatorics and its Applications, vol. 5, 10-36, 1992. Note: as described by Eades, the algorithm does not allow variable node size.
