    Matplotlib uses downsampling to speed up plotting and avoid clutter.

  3. Final Answer:

    To reduce the number of data points for faster and clearer plots -> Option D

  4. Quick Check:

    Downsampling = reduce points for clarity [OK]
Quick Trick: Downsampling cuts points to speed up and clean plots [OK]
