How would you optimize the performance of a Matplotlib or Seaborn visualization that is rendering a very large dataset with millions of points?

COVER // HOW WOULD YOU OPTIMIZE THE PERFORMANCE OF A MATPLOTLIB OR SEABORN VISUALIZATION THAT IS RENDERING A VERY LARGE DATASET WITH MILLIONS OF POINTS?

To optimize performance, I would utilize techniques like downsampling the data, using more efficient plot types, and leveraging Matplotlib’s built-in optimization flags. Additionally, using data aggregations or binning could significantly reduce the number of points plotted without losing meaningful insights.
