Salut Nicolas et Vincent, I am trying to use the graphviz functionalities you added in ticket #7004. So, I installed graphviz and the dot2tex spkg as explained in the documentation of layout_graphviz method, but I get the following error when I use it :
sage: g = Graph({2:[3,4]}) sage: g.layout_graphviz() Traceback (most recent call last): ... UnboundLocalError: local variable 'positions' referenced before assignment Are you able to make this (or any) example to work? How should I use it?
