PHP GraphViz Documentation

Question

Has anyone used graphviz-php and if so do they know where I can find any documentation regarding its usage/class structure etc?

Please note that this is the graphviz-php not the pear (image_graphviz).

Thanks

Answer 1

http://pear.php.net/package/Image_GraphViz/docs/latest/GraphViz/Image_GraphViz.html contains a usage example

Answer 2

I have found an explanation of the graphviz.php as below.

The GraphViz class allows for the creation of and the work with directed and undirected graphs and their visualization with AT&T's GraphViz tools.

  require_once 'Image/GraphViz.php';

  $graph = new Image_GraphViz();

  $graph->addNode(
    'Node1',
    array(
      'URL'   => 'http://link1',
      'label' => 'This is a label',
      'shape' => 'box'
    )
  );

  $graph->addNode(
    'Node2',
    array(
      'URL'      => 'http://link2',
      'fontsize' => '14'
    )
  );

  $graph->addNode(
    'Node3',
    array(
      'URL'      => 'http://link3',
      'fontsize' => '20'
    )
  );

  $graph->addEdge(
    array(
      'Node1' => 'Node2'
    ),
    array(
      'label' => 'Edge Label'
    )
  );

  $graph->addEdge(
     array(
       'Node1' => 'Node2'
     ),
     array(
      'color' => 'red'
   )
  );
  $graph->image();
