This donut chart displays the frequency of three languages—English, Spanish, and German—based on sums from a local JSON file. The chart includes a small legend-free design with labels positioned outside the arcs using custom polylines generated via D3’s `d3.arc` and `outerArc` centroid calculations. Data is loaded asynchronously with `d3.json` and parsed into a pie layout using `d3.pie`, while colors come from the `d3-scale-chromatic` scheme. The visualization filters to the top five entries (here, all three) and renders SVG paths with opacity and stroke styling.
