This pie chart visualizes student education levels and their associated math scores, using colored slices to represent each category. The chart is built with D3 v5 and rendered as an SVG, with the `pie()` and `arc()` generators creating the segments and the `scaleOrdinal` mapping colors to data. A legend on the right displays each education level alongside its corresponding math score. Data is loaded from a CSV file via a GitHub gist, and the code includes a video tutorial link in the README.
