Detailed Description

A "main" or "root" graph defines a namespace for a collection of graph objects (subgraphs, nodes, edges) and their attributes. Objects may be named by unique strings or by integer IDs.

agsubg finds or creates a subgraph by name.

agidsubg allows a programmer to specify the subgraph by a unique integer ID.

A new subgraph is initially empty and is of the same kind as its parent. Nested subgraph trees may be created. A subgraph's name is only interpreted relative to its parent.

A program can scan subgraphs under a given graph using agfstsubg and agnxtsubg.

A subgraph is deleted with agdelsubg (or agclose).

The agparent function returns the immediate parent graph of a subgraph, or itself if the graph is already a root graph.
