What is hypergraph: hierarchy for?

An example of a hypergraph: hierarchy is shown above

The Hypergraph is a picture of the nodes and their connections in Maya. A complex scene can look like a very intricate web of these connections. When you really need to know how a network of nodes isconnected, the Hypergraph gives you the most detailed view. There are two ways to view the Hypergraph, the hierarchy view and the connections view:

The hierarchy view shows the relationships between nodes as a tree structure.
The connections view shows how the nodes are connected as a web.You can have more than one Hypergraph window open at the same time, but you are still looking at the same scene with the same nodes and connections.
