• Combine several graph layouts (that already have layout information):

gvpack path/to/layout1.gv path/to/layout2.gv ... > path/to/output.gv

• Combine several graph layouts at the graph level, keeping graphs separate:

gvpack -g path/to/layout1.gv path/to/layout2.gv ... > path/to/output.gv

• Combine several graph layouts at the node level, ignoring clusters:

gvpack -n path/to/layout1.gv path/to/layout2.gv ... > path/to/output.gv

• Combine several graph layouts without packing:

gvpack -u path/to/layout1.gv path/to/layout2.gv ... > path/to/output.gv
