The video tutorial introduces contour plots, a method for visualizing 3D data on a 2D plot. It explains how to define a 3D function and create mesh grids using NP meshgrid. The tutorial covers plotting standard contour plots with color specifications and advanced techniques like using color maps and filled contour plots. The session concludes with a brief mention of other plot types and an introduction to deep learning.

What is the difference between a standard contour plot and a filled contour plot?

What additional features can be added to a contour plot for better visualization?
