This interactive Spotify dashboard presents three linked views of a music dataset: a sortable popularity leaderboard, a radar-chart comparison of genre audio features, and a correlation heatmap of track attributes. Users can switch between these views and adjust their parameters, such as sorting by genre or artist. The leaderboard uses a `d3.scaleBand` bar chart, while radar charts are built with `d3.select` and SVG polygons. The heatmap computes correlations with `jeezy`'s `arr.correlationMatrix` and applies `d3-scale-chromatic`'s `chroma.scale` for color. All views include interactive tooltips and animations.
