NAME

SYNOPSIS

    use Graph::Reader::Dot;
    use Graph;

    $reader = Graph::Reader::Dot->new();
    $graph = $reader->read_graph('mygraph.dot');

DESCRIPTION

Graph::Reader::Dot is a subclass of Graph::Reader, which defines the generic interface for Graph reader classes.

METHODS AND CONFIGURATION

    $reader = Graph::Reader::Dot->new();

    $graph = $reader->read_graph( $file );

RESTRICTIONS

• Default (graph) attributes in subgraphs (i.e. inside "{}") are not processed.
• Sub nodes as used by dot's "record" node shape are supported.
• Undirected graphs will be treated as directed graphs. This means that the "--" edge operator works as the "->" edge operator.
• Be aware that you are loosing scope information on writing back the graph.
• Multiple "node[]" or "edge[]" statements in the same scope are not correctly supported.
