Raise PySparkValueError for unsupported plot kinds
Why are the changes needed?
Previously, unsupported plot kinds raised a raw KeyError, which was unclear. This change adds explicit validation and raises a descriptive PySparkValueError, improving user experience and debugging clarity.
Does this PR introduce any user-facing change?
Yes, when passing an invalid kind to DataFrame.plot, users now receive a clear PySparkValueError instead of a generic KeyError.
How was this patch tested?
Unit tests.
Was this patch authored or co-authored using generative AI tooling?
No.
