To get the most out of this book

Basic knowledge of Python is enough to understand the content in this book, except for Chapters 9, Developing Interactive Plots and Chapter 10, Embedding Plots in a Graphical User Interface. These two chapters deal with interactive plotting and embedded applications that need medium-level Python programming experience.

Many Python distributions automatically include Matplotlib, along with all its dependencies. If you have not installed any standard Python distributions, you can follow the installation process at https://matplotlib.org/users/installing.html to install Matplotlib and its associated dependencies.
