This pie chart visualizes the count of students from each major at UNT, with each slice colored and labeled with the student count in thousands. The data is loaded from a CSV file via `d3.csv`. The chart is rendered using React with D3 v5, employing `d3.pie` and `d3.arc` to generate the paths, `d3.scaleOrdinal` for colors, and SVG groups for the chart and legends.
