A donut chart displays the popularity of 36 languages from a dataset, but only the top 5 are labeled individually; all remaining languages are aggregated into a single "others" slice. The visualization uses d3.pie and d3.arc to generate the SVG paths, with d3.scaleOrdinal and d3.schemeDark2 for color encoding. Labels and connecting polylines are positioned using arc.centroid and a computed mid-angle, with text anchored left or right based on slice placement. Data is loaded via d3.json.
