graphml2gv (1)

graphml2gv [ -?v ] [ -ggname ] [ -ooutfile ] [ files ]

graphml2gv converts a graph specified in the GRAPHML format to a graph in the GV (formerly DOT) format.

The following options are supported:

-v

Turns on verbose mode

-?

Prints usage information and exits.

-ggname

The string gname is used as the name of the generated graph. If multiple graphs are generated, subsequent graphs use the name gname appended with an integer.

-ooutfile

Prints output to the file outfile. If not given, graphml2gv uses stdout.

The following operand is supported:

files

Names of files containing 1 or more graphs in GRAPHML. 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 significantly, the conversion can only be at best approximate. In particular, GV currently has no notion of hyperedges or edges containing graphs.

At present, graphml2gv only supports the basic graph topology. Specifically, the <KEY> and <DATA> elements are not handled, though they could be.
