Hello, Jeremiah Willcock,

I have been looked the filtered_graph.

It said that "The num_vertices and num_edges functions do not filter before
returning results, so they return the number of vertices or edges in the
underlying graph, unfiltered".

Some times I need make new vertices from return value of num_vertices of
filtered graph, not underlying graph.

How can I do?
