gml2gv [ -? ] [ -ooutfile ] [ files ]
gml2gv converts a graph specified in the GML format to a graph in the
GV (formerly DOT) format.
The following options are supported:
-? Prints usage information and exits.
Prints output to the file outfile. If not given, gml2gv uses
The following operand is supported:
files Names of files containing 1 or more graphs in GML. If no files
operand is specified, the standard input will be used.
Return 0 if there were no problems during conversion; and non-zero if
any error occurred.
As both the graph and graphics models of GV and GML differ signifi-
cantly, the conversion is at best approximate. In particular, it is not
clear how multiedges are differentiated in GML, so multiedges are cre-
ated in GV with no user-available key. Also, no attribute information
is lost, in that any GML attributes that aren't converted to GV equiva-
lents are retained as attributes in the output graph.
