This choropleth map visualizes the world using a green color scale, where each country is rendered as an SVG path and is interactive. Clicking a country opens a Bootstrap modal displaying statistics about that nation, including the total number of albums, top genres, popular artists, and albums per year. The map is built with D3.js v5 and TopoJSON, using a Mercator projection (`d3.geoMercator`) and `d3.geoPath` to generate the shapes. Country names and ISO codes come from a TSV file, while geographic boundaries are loaded from a world-atlas JSON.
