Commercial graph layout software is available, e.g., from yWorks
(www.yworks.com, see yFiles package), ILOG (www.ilog.com), and
Tom Sawyer Software (www.tomsawyer.com).
The yFiles feature an implementation of one of the recent multi-level
force-directed graph layout algorithms that can draw very large graphs
If you want to implement one yourself (non-trivial), this one is
of high quality:

A similar (though not quite as successful) method has recently been
included in Mathematica.
