This pie chart visualizes the distribution of stress levels among students, categorizing responses as Low, Moderate, High, or Very High. It uses d3.pie and d3.arc to generate the pie slices, d3.rollups to aggregate the CSV source data, and d3.scaleOrdinal with d3.schemeCategory10 for coloring. A legend and white stroke separators clarify the categories, with d3.arc centroid positioning for labels. The visualization renders as static SVG.
