 boolean randomlyInitialized,
 double naturalEdgeLength,
 double springConstant,
 double stopEnergy)

fruchtermanReingoldLayout

arrangeByLayout

public static void arrangeByLayout(Graph graph,
 HashMap<String,PointXy> layout)

circleLayout

public static void circleLayout(Graph graph,
 int centerx,
 int centery,
 int radius)

Arranges the nodes in the graph in a circle.

Parameters:

centerx - The x coordinate for the center of the layout.

centery - The y coordinate for the center of the layout.

radius - The radius of the circle in pixels; a good default is 150.

arrangeBySourceGraph

public static boolean arrangeBySourceGraph(Graph resultGraph,
 Graph sourceGraph)

Arranges the nodes in the result graph according to their positions in the source graph.

Returns:

true if all the nodes were arranged, false if not.
