Could you post the inclued output (in the /tmp/ dir) ?

And if you can, the php code?

this code reproduce:

 abstract class abstractApplication {
 	private static $instance;
 	
 	protected $resourceProxy;
 	
	final public static function getInstance() {
		$calledClass = get_called_class();
		if (!isset(self::$instance)) {
			self::$instance = new $calledClass;
		}
		
		return self::$instance;
	}
	
    final protected function __construct() {
    }

	final public function getResource($resource) {
		$cacher = self::$instance;
		
		$cachedResource = $a->resourceProxy->get($resource);
		
		return($cachedResource);
	}
	
	abstract public function execute();
}

class httpApplication extends abstractApplication { 
    public function initialize() {
    } 

    public function execute() {
    }
    
    public function canDoAction($action) {
    }
    
	public function login() {
	}
}

class websiteApplication extends httpApplication { 
    public function initialize() {
    } 

    public function execute() {
    }
    
    public function canDoAction($action) {
    }
    
	public function login() {
	}
}

class otherBaseClass {
	public function doSomething() {
		
	}
}

class otherDerived extends otherBaseClass {
	public function doSomething() {
		
	}	
}

$application = httpApplication::getInstance();

echo "end";

------------------------------------------------

espect:

object->abstractApplication->httpApplication->websiteApplication
|
+->otherBaseClass->otherDerived

If you have any ideas on improving the visual aspects of the dump, please feel free to muck around with the gengraph.php output and send me a patch.
