Do you have a use-case?

Hmmm, yeah. This is an interesting comment because the process you've described is essentially exactly what I am considering building. CSV + prompt -> chart. I've already done a few examples with LLM's generating structured data that renders to a SVG, but haven't tried it for charts yet. No doubt the majority of users would not be technical enough to work with matplotlib as you're describing, so I wonder if there is alpha in making something like this for total non-tech people.

Thanks for the input!
