SYNOPSIS use Graph::Reader::TGF; my $obj = Graph::Reader::TGF->new; my $graph = $obj->read_graph($tgf_file); METHODS "new()" Constructor. This doesn't take any arguments. Returns Graph::Reader::TGF object. "read_graph($tgf_file)" Read a graph from the specified file. The argument can either be a filename, or a filehandle for a previously opened file.
