This interactive donut chart visualizes YouTube channel analytics, showing the distribution of a selected metric (Views, Likes, Comments, Watch Time, or Subscribers) across the top N weeks, with remaining weeks aggregated into an "Other" slice. Users adjust the metric and slice count via dropdown and number input controls. The visualization uses D3’s `pie`, `arc`, `scaleOrdinal` with `schemeTableau10`, and `csvParse` to load and process data from a GitHub-hosted CSV file, rendering slices, leader lines, labels, and a legend as SVG.
