NAME

6       Graph::Easy::Layout::Force - Force-based layouter for Graph::Easy

SYNOPSIS

9               use Graph::Easy;
10
11               my $graph = Graph::Easy->new();
12
13               $graph->add_edge ('Bonn', 'Berlin');
14               $graph->add_edge ('Bonn', 'Ulm');
15               $graph->add_edge ('Ulm', 'Berlin');
16
17               $graph->layout( type => 'force' );
18
19               print $graph->as_ascii( );

DESCRIPTION

30       "Graph::Easy::Layout::Force" contains routines that calculate a force-
31       based layout for a graph.
32
33       Nodes repell each other, while edges connecting them draw them
34       together.
35
36       The layouter calculates the forces on each node, then moves them around
37       according to these forces until things have settled down.
38
39       Used automatically by Graph::Easy.
