Hi,

First of all, thanks for a great library with great documentation. I'm just starting with graph-tool but so far it looks really nice. I have previously used the now unmaintained BGL-python bindings and for me it is good that graph-tool seems to have some similarities in its API.

Thanks!

My question is: I often have large graphs where I cannot display vertex labels in the output for reasons of space. I would really love to draw these graphs to a format where I could hover with the mouse to produce tool tips to show vertex labels, etc... Is this possible?

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.
