What's matplotlib?

Matplotlib is an extensively used plotting library, especially designed for 2D graphs. From this library, we will focus on using the pyplot module, which is a part of the API of matplotlib and has MATLAB-like methods, with direct NumPy support. For those of you not familiar with MATLAB, it has been the default mathematical notebook environment for the scientific and engineering fields for decades.

The method described will be used to illustrate a large proportion of the concepts involved, and in fact, the reader will be able to generate many of the examples in this book with just these two libraries, and using the provided code.
