Changelog

UNRELEASED

Changed

  • VegaLiteWriter.render_chart() and render_altair() now accept validate, height, and width as explicit keyword arguments. height and width default to None, which preserves whatever dimensions ggsql produces. validate defaults to False (same behavior as before, now a named parameter).

0.3.2

Changed

  • Upgraded to ggsql Rust crate v0.3.2.
  • render_altair() and VegaLiteWriter.render_chart() now default to validate=False when creating Altair chart objects. This avoids ValidationErrors for valid specs (e.g., boxplots) that use Vega-Lite features not yet reflected in Altair's schema. Pass validate=True to re-enable.
  • When Altair can't deserialize a spec into the expected chart subclass (e.g., LayerChart), the converter now falls back to altair.Chart instead of raising. The chart still displays correctly; only Altair-level round-tripping (.to_dict()) is lost.

0.3.1

Changed

  • Upgraded to ggsql Rust crate v0.3.1.
  • Replaced polars with Arrow (via pyarrow) for the Rust↔Python data bridge. DuckDBReader.execute_sql(), Spec.data(), Spec.layer_data(), and Spec.stat_data() now return pyarrow.Table instead of polars.DataFrame. DuckDBReader.register() accepts pyarrow.Table (polars DataFrames are still accepted via automatic conversion). Custom readers returning polars DataFrames from execute_sql() continue to work without changes.
  • Runtime dependency changed from polars to pyarrow.

0.2.7

Synced with ggsql Rust crate v0.2.7.

0.1.4

Initial release.
