use GraphViz::Data::Grapher; my $graph = GraphViz::Data::Grapher->new($structure); print $graph->as_png;
Data::Dumper can help by representing the structure as a text hierarchy, but GraphViz::Data::Grapher goes a step further and visualises the structure by drawing a graph which represents the data structure.
Arrays are represented by records. Scalars are represented by themselves. Array references are represented by a '@' symbol, which is linked to the array. Hash references are represented by a '%' symbol, which is linked to an array of keys, which each link to their value. Object references are represented by 'Object', which then links to the type of the object. Undef is represented by 'undef'.
my $graph = GraphViz::Data::Grapher->new([3, 4, 5], "Hello");
# Print out a PNG-format file print $graph->as_png; # Print out a PostScript-format file print $graph->as_ps;
