This pie chart visualizes student records, showing the distribution of math scores as proportional slices. The chart renders in SVG using D3 v5, with a scaleOrdinal color scheme and pie/arc generators to create segments. Each slice displays its value as a text label, and a legend on the right pairs color swatches with student results and corresponding numeric values. Data is loaded as CSV from a remote URL and processed asynchronously, with percentages formatted using d3.format.
