Description

Reason or Problem

examples/xarray-spatial_classification-methods.ipynb uses datashader only for rendering (shade with matplotlib colormaps). There is no rasterization to replace here.

Proposal

  • Remove the datashader import.
  • Replace shade with matplotlib imshow using the same colormaps.
  • Update any prose that mentions datashader.
  • Re-execute the notebook so outputs regenerate cleanly.

Done when

  • The notebook runs top to bottom with no datashader import and produces the expected plots.

Part of removing datashader as a dependency; final packaging removal is tracked in #3450.

Research direction

Open examples/xarray-spatial_classification-methods.ipynb and run the notebook to inspect its current rendering cells and outputs. Replace the datashader-based rendering with matplotlib imshow using the existing colormaps, update prose that mentions datashader, and re-execute it. Done means the notebook runs top to bottom, has no datashader import, and produces the expected plots.
