SYNOPSIS

9               use Graph::Easy;
10
11               my $graph = Graph::Easy->new();
12
13               my $bonn = Graph::Easy::Node->new(
14                       name => 'Bonn',
15               );
16               my $berlin = Graph::Easy::Node->new(
17                       name => 'Berlin',
18               );
19
20               $graph->add_edge ($bonn, $berlin);
21
22               $graph->layout();
23
24               print $graph->as_ascii( );
25
26               # prints:
27
28               # +------+     +--------+

DESCRIPTION

33       "Graph::Easy::Layout::Grid" contains routines that calculate cell sizes
34       on the grid, which is necessary for ASCII, boxart and SVG output.
35
36       Used automatically by Graph::Easy.

EXPORT

39       Exports nothing.

METHODS

45       This module injects the following methods into Graph::Easy:
46
47   _prepare_layout()
48               my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();
49
50       Returns two hashes ($rows and $cols), containing the columns and rows
51       of the layout with their nec. sizes (in chars) plus the maximum
52       framebuffer size nec. for this layout. Also returns reference of a list
53       of all cells to be rendered.
