NAME

HTML::InfoVis::Graph - Generate a JSON structure suitable for loadJSON classes

SYNOPSIS

  use HTML::InfoVis;
  
  my $graph = HTML::InfoVis::Graph->new;
  $graph->add_edge( 'foo' => 'bar' );
  
  print "var json = " . $graph->as_json . "\n";

DESCRIPTION

HTML::InfoVis::Graph is used to generate a JSON structure suitable for loading by any InfoVis Javascript object that has the loadJSON method.

This is a basic first implementation, designed to prove the concept of converting Perl graphs into InfoVis graphs.

It provides a few Graph-like methods to populate the graph, and a single method for generating an anonymous JSON structure representing the graph.

METHODS

new

  my $graph = HTML::InfoVis::Graph->new(
      Graph->new,
  );

The default constructor takes a single optional param of a Graph object that represents the graph structure.

Returns a new HTML::InfoVis::Graph object.

add_node

  $graph->add_node( 'foo' );

The add_node method is a pass-through method to the underlying Graph add_vertex method.

add_edge

  $graph->add_edge( 'foo' => 'bar' );

The add_edge method is a pass-through method to the underlying Graph add_edge method.

as_json

  my $json = $graph->as_json;

The as_json method generates a serialized anonymous JSON structure that represents the graph in a form suitable for loading by any InfoVis loadJSON method.

Because it is generated anonymously, if you wish to assign it to a variable you will need to do that yourself in your JavaScript template.
