void Layout_ForceDirected (  TOptFDP  method = FDP_DEFAULT, TFloat  spacing = 0.0 )  throw (ERRejected) [inherited]

Refine a given graph drawing according to a model of forces. Parameters: method  A TOptFDP value specifying the applied method spacing  The minimum node distance or 0 This refines a given straight-line drawing by modelling the nodes as loaded particles repelling each other, and the edges as elastic bands keeping its end nodes close to each other. Node are moved according to the unbalanced forces in the current drawing. Depending on the concrete method, there can be additional restrictions on the node movements.
