In this video, we have covered how to make a 2D Heatmap using Matplotlib in Python. 
What is a 2D Heatmap?
A two-dimensional heatmap is a data visualization technique that uses colors to illustrate the magnitude of a phenomenon. The Matplotlib module in Python can be used to create 2-D Heatmaps.

It can be done in three ways:
1 - Using imshow() function
2 - Using seaborn Library
3 - Using matplotlib.pyplot.pcolormesh() Function
