Graph::Flowchart Description

Graph::Flowchart is a Perl module that can generate easily flowcharts as Graph::Easy objects. Graph::Flowchart is a Perl module that can generate easily flowcharts as Graph::Easy objects.SYNOPSIS use Graph::Flowchart; my $flow = Graph::Flowchart->new(); print $flow->as_ascii();This module lets you easily create flowcharts as Graph::Easy objects. This means you can output your flowchart as HTML, ASCII, Boxart (unicode drawing) or SVG.ClassesThe nodes constructed by the various add_* methods will set the subclass of the node according to the following list:startThe start block.endThe end block, created by finish().blockOrindary code blocks, f.i. from $b = 9;.if, for, while, untilBlocks for the various constructs for conditional and loop constructs.subFor sub routine declarations.useFor use, no and require statements.goto, break, return, next, last, continueBlocks for the various constructs for jumps/returns.true, false, goto, call, return, break, next, continueClasses for edges of the true and false if-branches, and for goto, as well as sub routine calls.Each class will get some default attributes, like if constructs having a diamond-shape.You can override the graph appearance most easily by changing the (sub)-class attributes: my $chart = Graph::Flowchart->new(); $chart->add_block('$a = 9;'); $chart->add_if_then('$a == 9;', '$b = 1;'); $chart->finish(); my $graph = $chart->as_graph();Now $graph is a Graph::Easy object and you can manipulate the class attributes like so: $graph->set_attribute('node.if', 'fill', 'red'); $graph->set_attribute('edge.true', 'color', 'green'); print $graph->as_html_file();This will color all conditional blocks red, and edges that represent the true branch green.
