I have successfully uploaded seaborn-related Jupyter notebooks to my github/gist repo.
They render correctly on github. In this case, I saved the notebook with all cells executed and charts rendered.
When trying this with a notebook that is plotly-based and the cells have been executed prior to saving, they do not load on github/gist.
When I use non-executed notebook cells throughout, it does load and I can see the whole notebook. It just doesn’t contain the rendered cells.
My workaround will be to instruct the user to execute the cells in a notebook viewer in order to see them. Not a big deal, just something to share with the community.
