A few more ideas!

Thank you for your wonderful effort!

It would be fantastic to see the tool evolving to be more accessible for keyboard/screen reader users, and support imports for Excel sheets or any other spreadsheets.

Besides, I would love the tool to ask users for a specific need that a chart needs to meet — showing comparison, composition, distribution, relationship or change — and then suggest a type of visualization that would fit best. Once the result is there, we could perhaps use some knobs to tweak the outcome slightly without rewriting the prompt entirely.
