Hybrid Hierarchies

So if we have continuous hierarchies and discrete hierarchies, what about hybrid hierarchies? Just like we have discrete event, continuous and hybrid simulation, can we have hierarchies that are hybrid? A discrete hierarchy is like a mathematical graph, with nodes and arcs, but no spatial or temporal attributes (except for demonstrational purposes). A continuous hierarchy exists in time and space, but it's difficult to show connections or differences between arcs and nodes. So we need a hybrid graph, in ink and paper, or a road network. We create a hybrid hierarchy by placing stuff representing a graph (a discrete thing) onto a continuous media.
