Description copied from interface: GraphLayoutEngine

This method takes a graph and a Hashtable with the nodes that cannot be moved and returns a Hashtable with the coordinates of the nodes after doing the layout.

Specified by:

layoutGraph in interface GraphLayoutEngine

Parameters:

graph - The graph that needs to be layed out

fixedNodes - A Hashtable containing Node objects as keys, and Points as elements, which specify the coordinates of the non-movable nodes

Returns:

a Hashtable with Node objects as keys and Point objects as coordinates for the nodes.
