Research direction

Start with docs/source/user_guide/fire.ipynb and run the notebook to inspect its current outputs. Replace the datashader imports and shade/stack/Images usage with matplotlib, update prose cells that mention datashader, and re-execute the notebook. Done means it runs top to bottom without a datashader import and produces the expected plots and regenerated preview.

Description

area:spectral documentation user-guide-example

Reason or Problem

docs/source/user_guide/fire.ipynb uses datashader only for rendering (shade/stack/Images). There is no rasterization to replace here.

Proposal

  • Remove the datashader imports.
  • Replace shade/stack/Images with matplotlib.
  • Update any prose cells that mention datashader.
  • Re-execute the notebook so outputs and the preview image 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.
