- This example shows a user-defined hierarchical layout. If the user defines levels for nodes but does not do so for
- all nodes, an alert will show up and hierarchical layout will be disabled. Either all or none can be defined.
- If the smooth curves appear to be inverted, the direction of the edge is not in the same direction as the network.
