I've noticed that the Graph library has changed in the new version, though the documentation and the examples have not been updated. I am trying to use the fruchterman_reingold algorithm. I am confused as to the new parameters topology, origin and extent that are passed to the function.

I think topology is given by xmin, ymin, xmax, ymax for a rectangular topology.

For the origin, I have used topology.center()

But I am at loss as to what the extent is and what I should assign it. Can someone please explain these new parameters and what values are expected.

Thank you.
