Overall straightforward. Before I approve, can you please respond to my comments?

LGTM! Thanks @AndresOrtegaGuerrero. You can proceed. If possible, could you maybe comment on Plotly's image download API? The plot comes with built-in PNG download. I'm wondering if the modebar could be modified (in a future PR) to include custom buttons for other common formats (likely still using JS).

I used https://plotly.com/python-api-reference/plotly.io.html?highlight=io#module-plotly.io , i dont know if the other option can be modified.
