running `dj.Diagram(sgc.Session) - 1 + 2` requires compatible `pydot` and `networkx` libraries

Describe the bug A clear and concise description of what the bug is.

I just created a new conda environment with the most recent spyglass version. I ran dj.Diagram(sgc.Session) - 1 + 2 in the 02_Insert_Data.ipynb and found below error. Error was resolved when I reinstalled compatible versions of pydot and networkx by pip install pydot==1.4.2 networkx==2.5.
