	Use a `spring-embedder <http://en.wikipedia.org/wiki/Force-based_algorithms_(graph_drawing)>`_ algorithm for

		* ``num_iterations [=100]`` (int): the number of times to update the positions of nodes based on the forces among them.
		* ``bbox [=(0,0,100,100)]`` (:py:class:`tuple`): the spatial box into which all nodes should be confined.
