May not exactly be what you're looking for, but I have used the TeX
`xypic' package, which comes with `print/teTeX', for drawing directed
graphs. From your other messages, I understand your graphs have a
large number of vertices. I don't know how `xypic' scales for large
graphs. The ones I've used it for were quite small. Moreover, the
input format for `xypic' is similar to a matrix in LaTeX. The package
essentially views the graph as a matrix, each of whose entries is a
label for a vertex together with vectors that represent the edges
starting from that vertex.
