SYNOPSIS

            

              
              
use Graph::Easy;
my $graph = Graph::Easy->new();
my $bonn = Graph::Easy::Node->new(
        name => 'Bonn',
);
my $berlin = Graph::Easy::Node->new(
        name => 'Berlin',
);
$graph->add_edge ($bonn, $berlin);
$graph->layout();
print $graph->as_ascii( );

_prepare_layout()

            

              
              
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.
