This pie chart visualization displays the proportional breakdown of categorical data loaded from a remote CSV file. Constructed with D3.js v7, the SVG graphic uses `d3.pie` to compute arc segments and `d3.arc` for path geometry, with `d3.scaleOrdinal` and `d3.schemeCategory10` providing categorical colors. A legend, including color swatches and labels, is positioned on the left side, while the chart title appears above. The code loads data via `d3.csv` and renders all elements as SVG paths and text nodes.
