After nearly killing myself (in frustration) installing Sage 8.4 from source on OSX 10.14.1 (Mojave), I discover that a graph plotting command that I frequently use has vanished, breaking a number of my own programs.
Previously (on SageMath up to 8.2) I would do
from sage.graphs.graph_plot import _circle_embedding
in order to access this.
Now I just get
ImportError: cannot import name _circle_embedding
I can relatively easily replace this particular function myself, but if it were something more complicated, I would be at a loss to know how to track down the cause for its disappearance and figure out how to get it back.
So I guess the questions are: has it only vanished for me due to a botched or incomplete installation, or has it somehow been removed from Sage? In either case, how can I recover it?
