Category Hierarchy

A hierarchy is the opposite of a network. Opposite?

In graph theory, a "network" would be just a graph (you may want it to be a connected graph.) A "hierarchy" would be something like a "directed acyclic graph" (directed tree) or just a graph with specific constraints.

See NetworkVsHierarchy for discussion.
