One of the most popular and powerful plotting libraries in Python is matplotlib. If you are familiar with the programming language Matlab, then you will find matplotlib to be a very quick study.

Note

To learn more about matplotlib, visit the following website:  http://matplotlib.org

Before we can get started using matplotlib, we will first need to install it either through PyCharm or through the command line:

pip install matplotlib

Next, we will need to import the module and call the %matplotlib inline function to view plots directly inside of the Jupyter Notebook:
