This is not a duplicate of 2257! I would like to initialize a graph with a text-file, but then I want to be able to move the verticles per drag and drop (almost like diagram.ly supports it).

The only function of sage, which is almost like drag and drop, is "@interact def f(r=(2..4), h=(1..8)): g = graphs.BalancedTree(r,h) g.show(graph_border=True)". But I would like to be able to move the verticles. This seems to be impossible with SAGE. Nevertheless, SAGE is a great piece of software.
