.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBGraph::Writer::daVinci\fR is a class for writing out a directed graph
in the file format used by the \fIdaVinci\fR tool.
The graph must be an instance of the Graph class, which is
actually a set of classes developed by Jarkko Hietaniemi.

This doesn't take any arguments.
.SS "\fBwrite_graph()\fP"
.IX Subsection "write_graph()"
Write a specific graph to a named file:
.PP
.Vb 1
\&  $writer\->write_graph($graph, $file);

The \f(CW$file\fR argument can either be a filename,
or a filehandle for a previously opened file.
