This visualization displays the genre distribution of Spotify’s Top 50 songs as a pie chart, with percentage labels on each slice and a color-coded legend. It loads CSV data via `d3.csv`, aggregates counts with `d3.rollup`, and renders SVG paths using `d3.pie` and `d3.arc`. The chart applies a Tableau10 color scheme from `d3.scaleOrdinal` and positions text labels at arc centroids.
