For that, I had to do the following things: Make sure import tkinter works (here how I did it, no root privileges needed). Matplotlib is a module for Python that focuses on plotting and data visualization. All video and text tutorials are free. Creating a line chart in Python is a little confusing to. This is a useful way to visualize the data, but the plot's legend will use the same marker sizes by default and it can be quite difficult to discern the color of a single point in isolation. Computers can automatically classify data using the k-nearest-neighbor algorithm. datasets import load_boston # load boston dataset # with features and house. If you are a scientist, programmer, software engineer, or student who has working knowledge of matplotlib and now want to extend your usage of matplotlib to plot complex graphs and charts and handle large datasets, then this book is for you.
