An interactive SVG bar chart visualizes Spotify artists and their albums, sorted by monthly listeners, with each artist bar expanding into individual album rows. Clicking an artist opens an animated info panel displaying their total streams, listener counts, and album details. Built with React 19 and D3.js v7, the visualization uses staggered entry transitions, gradient fills, and hover effects. Data is loaded from a CSV file and processed into a hierarchical artist-album structure before being rendered.
