I've added a unit test, however it reveals some other issues. I'll comment inline. |

If you remove the y.domain here, the chart works in preview but crashes in node tests. I don't understand what the difference might be.

This is how the chart looks like in preview. But it crashes in node. Is apache-arrow behaving differently in the browser?

Ref. #2155 (review)
Note that in the case of DuckDB-Wasm, we default
config.query.castBigIntToDoubleto true, so we shouldn’t see BigInt in practice with DuckDB, but we might still see it when loading Arrow or Parquet files.
