NAME

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

SYNOPSIS

               use Graph::Easy;

               my $graph = Graph::Easy->new();

               $graph->add_edge ('Bonn', 'Berlin');
               $graph->add_edge ('Bonn', 'Ulm');
               $graph->add_edge ('Ulm', 'Berlin');

               $graph->layout( type => 'force' );

               print $graph->as_ascii( );

               # prints:

               #   +------------------------+
               #   |                        v
               # +------+     +-----+     +--------+
               # | Bonn | --> | Ulm | --> | Berlin |

DESCRIPTION

       "Graph::Easy::Layout::Force" contains routines that calculate a force-based layout for a
       graph.

       Nodes repell each other, while edges connecting them draw them together.

       The layouter calculates the forces on each node, then moves them around according to these
       forces until things have settled down.

       Used automatically by Graph::Easy.

EXPORT

       Exports nothing.

SEE ALSO

       Graph::Easy.

METHODS

       This module injects the following methods into Graph::Easy:

   _layout_force()
       Calculates the node position with a force-based method.
