Ah, so the actual display size is a browser (or maybe Jupyter?) issue then.
I tried in Firefox, and with Jupyter Lab it looks pretty bad. The image scrolls vertically …
In Chrome it displays in full, except that it is so big, it does not fit on the screen.
In Safari, it is majorly messed up:
This may not be an issue with igraph, but it is still a concern for us, as all that a user sees is that matplotlib output is not affected, but igraph output is a pain to deal with.
