This donut chart displays the distribution of song counts by language, showing the top nine languages individually and aggregating all remaining languages into an "Others" slice. Clicking the "Others" segment replaces the view with a zoomed-in breakdown of those remaining languages. The visualization is built with D3 v6 (including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with `d3.schemeTableau10`), renders as an SVG, and uses a custom tooltip for hover details on each slice.
