This pie chart visualizes the count of students from each major at UNT, displaying each segment’s value in thousands both inside the chart and in a legend. It loads CSV data from a GitHub gist using `d3.csv`, then processes it with `pie` and `arc` generators to create SVG paths. The chart applies `scaleOrdinal` for color mapping and uses `arc.centroid` to position labels, with a legend built from grouped `rect` and `text` elements.
