This world map visualization displays the geographic distribution of music album counts, using a green color scale where darker shades represent higher numbers of albums per country. Users can zoom and pan the map, and hovering over a country reveals a tooltip with its name and album count, while clicking opens a Bootstrap modal showing detailed country statistics. The visualization is built with D3 v5, using `d3.geoMercator` for projection, `d3.geoPath` to render country shapes from TopoJSON data from world-atlas, and a linear scale for coloring. Country-specific album data is loaded from a local JSON file.
