In the process of solving problems by using machine learning methods, you will definitely encounter scenarios that require drawing data. Matplotlib is an open source drawing library that supports Python language. As it supports rich drawing types, simple drawing methods and complete interface documentation, it is popular among Python engineers, researchers and data engineers. What's more, Matplotlib has a very active community and stable version iterations. When we are learning machine learning courses, mastering the use of Matplotlib is undoubtedly one of the most important preparations. So, in this lab, we will learn how to use Matplotlib to draw 2D and 3D graphics.
