I wrote a short post on how to visualize proteins using gradio as discussed with @osanseviero

Let me know what you think :)

[osanseviero]

As discussed in a DM, we'll review it here first and once ready we'll have a Gradio Guide with same content. I will review this Friday of next week but maybe @abidlabs is interested in reviewing as well! :partying_face:

Thank you for the contribution!!

All requested changes have been incorporated. I also removed the duplicate id for the post (there was already a folder assets/94_xx so I changed it to the first free number (98).
