📝 Walkthrough

Walkthrough

Two changes modify how PySpark DataFrames are processed in VegaFusion chart creation and update the related dependency. The chart module now returns a VegaFusion ExternalDataset descriptor instead of a raw Arrow schema for PySpark inputs, using protocol='spark' and an Arrow schema derived from spark_df.schema. The deepnote-vegafusion dependency minimum version bumps from 2.0.8 to 2.1.0, maintaining the same upper bound. Control flow and error handling remain unchanged.
