I have  a few ContainerNodes in my Diagram. These ContainerNodes inturn contain a few shape nodes. If I add shape nodes to the container nodes without incrementing the position information, all the nodes are stacked on top of each other in the container.
Initially the diagram will not conatin any links and user will be adding links manually.
Is there a layout that will lay out the Diagram recursively so that all the shape nodes will be neatly laid out horizontally within the container and the container nodes will be laid out vertically one above the other?

Thanks.
