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.
