Description

Contributor guide

Research direction

The issue requests adding support for Polars DataFrames as input to Prophet. To start, examine how Pandas DataFrame input is currently handled in the codebase, particularly in the `Prophet` class and any data validation functions (e.g., `prophet.py`). Look for existing conversion functions or type checks. Review the comments on the issue for any maintainer feedback or suggestions. Since no PR exists, you may propose a solution that wraps or converts Polars DataFrames to Pandas internally, or directly support Polars types. Investigate the performance implications and ensure compatibility with Prophet's forecasting logic.
