It seems like you call parent on a different method (setUpExtended() instead of setUp()). Are you sure this is correct? If so, you might want to change this to $this->setUpExtended().

    $this->Graph->setDirected(true);
    $graph = &$this->Graph;
    $dic = &$this->dic;

    $graph->addChild($main = new Node($dic, 'main', array(
      new Attribute($dic, 'shape', 'box'),
      new Attribute($dic, 'comment', 'this is a comment'),
    )));
    $graph->addChild(new Edge($dic, $main,
      $parse = new Node($this->dic, 'parse'), array(
        new Attribute($dic, 'weight', 8)
    )));
    $graph->addChild(new Edge($dic,
      $parse = new Node($dic, 'parse', Node::implicit()),
      $execute = new Node($dic, 'execute', Node::implicit())
    ));
    $graph->addChild(new Edge($dic, $main,
      $init = new Node($dic, 'init', Node::implicit()), array(
        new Attribute($dic, 'style', 'dotted')
    )));
    $graph->addChild(new Edge($dic, $main,
      $cleanup = new Node($dic, 'cleanup', Node::implicit())
    ));

    // XXX The original example creates the node after the edge referencing it.
    $graph->addChild($make_string = new Node($dic, 'make_string', array(
      new Attribute($dic, 'label', "make a\nstring"),
    )));

    $graph->addChild(new Edge($dic, $execute, $make_string));
    $graph->addChild(new Edge($dic, $execute,
      $printf = new Node($dic, 'printf', Node::implicit())
    ));
    $graph->addChild(new Edge($dic, $init, $make_string));

      new Attribute($dic, 'style', 'bold'),
      new Attribute($dic, 'label', '100 times'),
    )));

    $graph->addChild($compare = new Node($dic, 'compare', array(
      new Attribute($dic, 'shape', 'box'),
      new Attribute($dic, 'style', 'filled'),
      new Attribute($dic, 'color', '.7 .3 1.0'),
