How to plot a Numpy array using Matplotlib

Matplotlib is a cross-platform, data visualization and graphical plotting library for Python and its numerical extension NumPy. As such, it offers a viable open source alternative to MATLAB. Developers can also use matplotlib’s APIs (Application Programming Interfaces) to embed plots in GUI applications.

Numpy is a package for scientific computing. Numpy is a required dependency for matplotlib, which uses numpy functions for numerical data and multi-dimensional arrays as shown in the video.
