Given that this is a book on an advanced topic and the target audience will have installed matplotlib and the related dependencies more than once (most likely many times), detailed instructions will not be provided here. Two excellent books on matplotlib that cover this topic in their respective first chapters are Matplotlib for Python Developers and matplotlib Plotting Cookbook.

That being said, each chapter will have its own Git repository with scripts to install dependencies and set up Python's virtual environments. These scripts are a great resource, and reading them should provide additional details to those who seek to know more about installing matplotlib and the related libraries in Python virtual environments.
