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.
