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().

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

    $nullTitle = array(new Attribute($dic, 'title', NULL));

    // Global
    $g->addChild($start = new Node($dic, 'start', array(
      new Attribute($dic, 'shape', 'Mdiamond'),
    )));
    $g->addChild($end = new Node($dic, 'end', array(
      new Attribute($dic, 'shape', 'Msquare'),
    )));

    $nodes = array();

    // cluster0
    $g->addChild($cluster0 = new Cluster($dic, 0, array(
      new Attribute($dic, 'style', 'filled'),
      new Attribute($dic, 'color', 'lightgrey'),
      new Attribute($dic, 'label', 'process #1'),
    )));
    for ($i = 0 ; $i < 4 ; $i++) {

This code seems to be duplicated across your project.

      $nodeName = "a$i";
      $cluster0->addChild($nodes[$nodeName] = new Node($dic, $nodeName, $nullTitle));
    }

    // cluster1
    $g->addChild($cluster1 = new Cluster($dic, 1, array(
      new Attribute($dic, 'color', 'blue'),
      new Attribute($dic, 'label', 'process #2'),
    )));
    for ($i = 0 ; $i < 4 ; $i++) {

This code seems to be duplicated across your project.

      $nodeName = "b$i";
      $cluster1->addChild($nodes[$nodeName] = new Node($dic, $nodeName, $nullTitle));
    }

    $g->addChild(new Edge($dic, $nodes['a0'], $nodes['a1']));
    $g->addChild(new Edge($dic, $nodes['a1'], $nodes['a2']));
    $g->addChild(new Edge($dic, $nodes['a1'], $nodes['b3']));
