Description:

The VCG tool reads a textual and readable specification of a
graph and visualizes the graph. If not all positions of
nodes are fixed, the tool layouts the graph using several
heuristics as reducing the number of crossings, minimizing
the size of edges, centering of nodes. The specification
language of the VCG tool is nearly compatible to GRL, the
language of the edge tool, but contains many extensions. The
VCG tool allows folding of dynamically or statically specified
regions of the graph. It uses colors and runs on X11.
