How do you plot a large dataset in Python?

Visual Representation of Large Dataset using Matplotlib

  1. Figure() : It encompasses the entire visualization, which contains the x and y-axes.
  2. Axes() : These are the plots, the X, Y and Z axes (Z axis in certain cases).
  3. Axis() : This contains the numbers and help in generating the limits of the graph.
