how to use add_edge_list() and then add isolated vertices?

Hi,

I am using add_edge_list and it returns a vector map of vertices it has
added, but how do I add in
isolated vertices that have no edges (otherwise they would have been put
in there by add_edge_list). The
vector map of vertices is a mapping between integers -> string vertex
names. When I add in
  isolated vertices, they have string names that somehow have to be
incorporated into the
vmap that is returned by add_edge_list.

Any help appreciated.

Thanks!

You can just add them later via a call to Graph.add_vertex(). You can
include their names to the property map in the usual way.
