Data Visualization in Python

I would like to start this post with the good old quote "A Picture is worth a Thousand Words". That is what Data Visualization is all about. Data Visualization is an integral part of Data Science & Data Analysis. It is not only useful for us to understand the data, but also to present the insights of the data in the form of a graphical representation which is much easier to understand. Let's say that we are working on a Data Science project.
