@souro26 thanks for the PR! Does the same API works for versions below Altair v5? |

From the looks of it I think @souro26 used pure python logic and is not using an Altair API to make the type inference right? So I guess it might work for all versions |

Yes, the change avoids relying on Altair utility APIs and instead does explicit type assignment in python. I also verified it locally against Altair v4, and it behaves the same there, so it should work for all versions i think. |

Fixes #3233
Summary
Fixes a visualization failure with newer versions of Altair caused by the use of a removed utility function. This restores compatibility and allows visualization tests to pass on Altair v5+.
Bug / Issue
The Altair-based space visualization used
alt.utils.infer_vegalite_type_for_pandas, which was removed in Altair v5+.This caused visualization-related tests to fail with an
AttributeError,notably
test_call_space_drawer_full.Implementation
infer_vegalite_type_for_pandasutility.quantitativefor numeric valuesnominalfor non-numeric valuesThis aligns with Altair v5+ requirements when data is not provided as a pandas DataFrame
Testing
All visualization tests pass after the change.
Additional Notes
This change is limited to visualization components and is intended solely to
address dependency compatibility with newer Altair versions.
