Create visual representations of data that models real-world phenomena or processes : Line Charts

The video tutorial explains how to create line charts using the Matplotlib library in Python. It begins with an introduction to line charts and setting up a Python file. The tutorial then covers defining data arrays for variance and bias squared, followed by plotting these values along with total error on a line chart. The final section discusses adding labels, legends, and exporting the chart in various formats. The tutorial emphasizes the bias-variance tradeoff and demonstrates how to visualize it effectively using line charts.
