aiSee Gallery: Recursive Subgraph Nesting

aiSee supports recursive subgraph nesting. Each subgraph may have layout attributes of its own (layout algorithm, graph orientation, etc., see example). aiSee offers a number of graph hierarchy operations such as folding subgraphs to summary nodes. There are no special restrictions as to the maximum number of subgraphs or the depth of nesting. The example above shows 21 subgraphs on 4 levels.
