Research direction

Start with examples/animated_hillshade.py and inspect its datashader imports and the shade/stack rendering calls. Replace that rendering with matplotlib, then confirm the script runs without a datashader import; if it is no longer referenced, remove it and document why.

Written by the indexing model from the issue text.

Description

area:surface documentation user-guide-example

Reason or Problem

examples/animated_hillshade.py uses datashader only for rendering (shade, stack, the Elevation colormap). There is no rasterization to replace here.

Proposal

  • Remove the datashader imports.
  • Replace shade/stack rendering with matplotlib, or, if the script is stale and no longer referenced, remove it instead.
  • Confirm the script still runs (or document its removal).

Done when

  • The script runs with no datashader import, or it is removed with a note on why.

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