Graph::Easy.

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

  	my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();

Returns two hashes ($rows and $cols), containing the columns and rows of the layout with their nec. sizes (in chars) plus the maximum framebuffer size nec. for this layout. Also returns reference of a list of all cells to be rendered.
