Thanks!

Yes, you can do something similar to this. You can pass a list of
property maps as the "display_props" parameters to
graph_draw(). However, instead of a tooltip, it displays the property
values of the currently selected vertex in the lower left corner of the
screen.
Example:
>>> label = g.new_vertex_property("string")
>>> coordinates = g.new_vertex_property("vector<double>")
>>> graph_draw(g, display_props=[label, coordinates])
I hope this helps.
Cheers,
Tiago
