It's related to the latest plotly 6.0 release. Downgrading to 5 would fix the issue, also see: plotly/plotly.py#5027

Hi all,

for the case where you are building docs with sphinx

if you don't want to pin down plotly<6, the cleanest workaround that worked out for me was change the default renderer (as suggested in PedestrianDynamics/jupedsim#1536 (comment)), but do it with an env var so that you don't have to edit the cell code.

in the conf.py

# See: https://github.com/executablebooks/MyST-NB/issues/667
os.environ["PLOTLY_RENDERER"] = "sphinx_gallery"

hope it helps - Alex
