Why does Datashader use rasterization instead of plotting individual points when handling big data?

ARasterization is only used for small datasets.

BRasterization aggregates data into pixels, improving speed and reducing memory use.

CPlotting individual points is faster but less accurate.

DRasterization creates 3D plots automatically.

Step-by-Step Solution

Solution:

Step 1: Understand rasterization concept
Rasterization converts many points into pixel aggregates, reducing the number of objects to render.
Step 2: Recognize benefits for big data
This approach speeds up rendering and lowers memory use compared to plotting each point individually.
Final Answer:
Rasterization aggregates data into pixels, improving speed and reducing memory use. -> Option B
Quick Check:
Rasterization = aggregation for speed and memory [OK]

Quick Trick: Rasterization aggregates points for faster big data plotting [OK]
