NBviewer not rendering any images in notebook

[gracechuan2]

I have a jupyter notebook written in Julia and when I first rendered the notebook and its graphics in nbviewer, it worked perfectly fine in December 2022.

Now, none of the graphics appear properly, either dark shapes and missing plots.

This is a problem for microsoft edge and firefox, and probably all other browsers.

Link to my notebook: https://nbviewer.org/github/gracechuan2/contagion/blob/main/Network%20Contagion%20Simulations_final.ipynb

It seems to be an issue with other notebooks I found on the main page of nbviewer:
https://nbviewer.org/url/jdj.mit.edu/~stevenj/IJulia%20Preview.ipynb
https://nbviewer.org/github/SciRuby/sciruby-notebooks/blob/master/getting_started.ipynb

This seems to be a very significant bug so I hope it gets addressed soon!

@Carreau similar to #1037 and same for me (it used to work correctly)
