⚠️ This PR is a WIP ⚠️

I only made it a draft to discuss some implementation ideas.

Thanks!! I couldn't find any documentation on this but is it possible to get the Plotly chart to display as part of the Gradio chatbot interface?

is it possible to get the Plotly chart to display as part of the Gradio chatbot interface?

Sorry, I have been on holiday and I am returning back to work from tomorrow.

Before I left, I looked into embedding non-text widgets inside Gradio's ChatBot widget. I was surprised to learn that the widget only support static items.

You can display figures if you save them as image files on disk. This I managed to get working, but I am not sure this is what we want.

If we want a similar chat UI feeling as Streamlit offers, we either need to use a custom chatbot widget, implement our own container widget and see if we can add widgets similarly to a chatbot, or we have to go away from a typical chatbot flow, with different views for different scenarios in the prompt-completion flow.

What do you think?

EDIT: Note that it is possible to render plotly stuff using gradio.Plot (see here), but I am unable to add it to the gradio.Chatbot widget similarly as done with text or static images, which is unfortunate. But if it is OK to have this figure static, that is a potential workaround.

Gonna be impossible to add a way to change the generated SQL query code directly in the gradio.Chatbot widget though.

Made some progress on the proposed solution above.

I will be in transit for the rest of the day, but I can pick this up tomorrow and hopefully finish the draft :]

Made some more progress. But now I am losing internet access on the airplane, so will have to wait till tomorrow...

This looks really really good! Is it ready to merge? I'd love to try this out

@zainhoda No, not yet. I got a bit busy with finalising my thesis work. Im submitting my PhD thesis at the end of April, but I can take a look at this again after Easter. Stay tuned! :]
