Hi,
I think to avoid fdp to create huge graph, an option should be add to
integrate an m-limit :
Quoting http://www.jibble.org/piespy/
"The force model is modified so that a pair of nodes with separation
greater than m does not exert a repulsive force [Mut2003a]. This
alteration to the force model ensures that we do not end up with an
unnecessarily sparse graph drawing.

Metadata and Ontologies. Seventh International Conference on
Information Visualization (IV03), IEEE, pages 300-305, 2003.

Best regards.
