Graph::Writer::Dot(3pm) User Contributed Perl Documentation Graph::Writer::Dot(3pm)NAME
Graph::Writer::Dot - write out directed graph in Dot format
SYNOPSIS
use Graph;
use Graph::Writer::Dot;
$graph = Graph->new();
# add edges and nodes to the graph
$writer = Graph::Writer::Dot->new();
$writer->write_graph($graph, 'mygraph.dot');
DESCRIPTION
Graph::Writer::Dot is a class for writing out a directed graph in the file format used by the dot tool (part of the AT+T graphviz package).
The graph must be an instance of the Graph class, which is actually a set of classes developed by Jarkko Hietaniemi.
METHODS
new()
Constructor - generate a new writer instance.
$writer = Graph::Writer::Dot->new();
This doesn't take any arguments.
write_graph()
Write a specific graph to a named file:
$writer->write_graph($graph, $file);
The $file argument can either be a filename, or a filehandle for a previously opened file.

Graph::Writer::VCG - write out directed graph in VCG format
SYNOPSIS
use Graph;
use Graph::Writer::VCG;
$graph = Graph->new();
# add edges and nodes to the graph
$writer = Graph::Writer::VCG->new();
$writer->write_graph($graph, 'mygraph.vcg');
DESCRIPTION
Graph::Writer::VCG is a class for writing out a directed graph in the file format used by the VCG tool, originally developed for
Visualising Compiler Graphs. The graph must be an instance of the Graph class, which is actually a set of classes developed by Jarkko
Hietaniemi.
If you have defined any attributes for the graph, nodes, or edges, they will be written out to the file, as long as they are attributes
understood by VCG.
METHODS
new()
Constructor - generate a new writer instance.
$writer = Graph::Writer::VCG->new();
This doesn't take any arguments.
write_graph()
Write a specific graph to a named file:
$writer->write_graph($graph, $file);
The $file argument can either be a filename, or a filehandle for a previously opened file.
KNOWN BUGS AND LIMITATIONS
o Attributes with non-atomic values aren't currently handled. This includes the loc, classname, colorentry, and infoname attributes for
graphs, and the loc attribute for nodes,
o Can currently only handle graph, node, and edge elements and their attributes. So doesn't know about foldnode_defaults and things like
that.
