A group of nodes is surrounded by a frame, i.e. drawn in a box. The nodes inside the box are independent of the rest of the graph, i.e. there are no edges connecting nodes outside of the box with nodes inside the box or vice versa. The layout for the graph inside a box can differ from the layout of the outer graph.
The layout calculation for graphs with boxes is fast since the nodes inside the box are independent of the rest of the graph and the layout of the box is calculated separately.
