I would not have guessed that `"bar_length_units" = "data"` would be needed to make the `bar_length` apply to the subcoordinate axis. Even in the [bokeh docs](https://docs.bokeh.org/en/latest/docs/reference/models/annotations.html#bokeh.models.ScaleBar.bar_length_units:~:text=bar_length_units%20%3D%20%27screen%27): `"data" - the length...

@hoxbro , the first point doesn't seem like a blocker, correct?

started reviewing the notebook, but got stuck debugging the following: ```python ddf = dd.from_pandas(sgeodf, npartitions=2).pack_partitions(npartitions=100).persist() tf.shade(cvs.polygons(ddf, geometry='geometry', agg=ds.mean('population')), cmap=cc.kg) ``` ```bash --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) File ~/opt/miniconda3/envs/datashader-dev/lib/python3.12/site-packages/dask_expr/_core.py:467,...

They were intentional because the notebook mentions the `to_shapely` method. But I agree that it's a bit of a distraction so I've now removed those lines going back toward shapely.

@hoxbro, I think we can merge now
