NAME

Graph::Layout::Aesthetic::Force::MinEdgeIntersect - Try to make edges uncross

SYNOPSIS

  use Graph::Layout::Aesthetic;
  $aglo = Graph::Layout::Aesthetic->new($topology);
  $aglo->add_force("MinEdgeIntersect", 1);

DESCRIPTION

This module provides an aesthetic force for use by the Graph::Layout::Aesthetic package. It's normally implicitly loaded by using add_force.

The aesthetic force is that crossed edge midpoints repel each other with constant force. The code only works in two dimensions, so it will throw an exception if you try to associate this force with a layout that's not two-dimensional.

The old aglo documentation describes this aesthetic as using a inverse distance force, but that's actually not what the code does.

METHODS

This class inherits from Graph::Layout::Aesthetic::Force and adds no methods of its own.

EXPORT

None.
