Yes, just do: graph_draw(g, display_props=[labels]) When you hover over a vertex, the corresponding label will appear on the lower right corner. The "display_props" takes a list of property maps. You can pass many, and all of them will be displayed. Best, Tiago -- Tiago de Paula Peixoto <[email protected]>
