Any interest in supporting polars instead of just pandas?

I think in the plots.py functions there'd need to be a check if data is either pandas or polars and then _create_chart_data_agg would be for pandas and there'd be a _create_chart_data_agg_pl function that would do the same thing except from polars.

This is just an example, of course there are a bunch of other functions to contend with.
