Important: The networks package has been deprecated.Use the superseding command GraphTheory[Graph] instead.

This procedure generates void graphs, i.e. graphs with n vertices and no edges. (Specific vertices may be provided as a set.) It is normally loaded via the command with(networks) but may also be referenced using the full name networks[void](...).
