This D3.js pie chart displays browser market share data for Q3 2025, loaded from a CSV file hosted on a GitHub Gist. Each slice is colored using `d3.scaleOrdinal` with `d3.schemeSet2`, and labeled with the percentage value. The chart uses `d3.pie` and `d3.arc` to generate the slices, with white stroke separating them. A legend on the right, built with SVG rectangles and text, identifies each browser. The visualization is rendered entirely as SVG within a 960x500 canvas.
