NAME Map::Tube::GraphViz - GraphViz output for Map::Tube. SYNOPSIS use Map::Tube::GraphViz; my $obj = Map::Tube::GraphViz->new(%params); $obj->graph($output_file); METHODS "new(%params)" Constructor. * "callback_edge" Edge callback. Default value is this: sub { my ($self, $from, $to) = @_; $self->{'g'}->add_edge( 'from' => $from, 'to' => $to, ); return; } * "callback_node" Node callback. Default value is \&Map::Tube::GraphViz::Utils::node_color. * "driver" GraphViz2 driver. Default value is 'neato'. * "g" GraphViz2 object. Parameters 'g' and 'name' cannot combine. Default value is this: GraphViz2->new( 'global' => { 'directed' => 0, }, $name ? ( 'graph' => { 'label' => $name, 'labelloc' => 'top', }, ) : (), ); * "name" Name of map. Parameters 'g' and 'name' cannot combine. Default value is Map::Tube->name or undef. * "output" GraphViz2 output. It is required. Default value is 'png'. Possible values are every formats supported by GraphViz2 module. See L. * "tube" Map::Tube object. It is required. Default value is undef. "graph($output_file)" Get graph and save it to $output_file file. Returns undef. ERRORS new(): Parameter 'tube' is required. Parameter 'tube' must be 'Map::Tube' object. Parameter 'output' is required. Unsupported 'output' parameter '%s'. From Map::Tube::GraphViz::Utils::color_line(): No color for line '%s'. From Class::Utils::set_params(): Unknown parameter '%s'.
