This map visualization displays the geographic distribution of music albums, with country colors shaded by count according to a green scale. It shows a choropleth of world data where users can hover to see precise album counts and click to open a modal with detailed statistics about genres, artists, and yearly totals. The implementation uses D3 v5 with d3.geoMercator projection, d3.geoPath, and a d3.scaleLinear color scale, pulling TopoJSON country boundaries from world-atlas and loading country album counts from a local JSON file. Zooming is enabled via d3.zoom, with Bootstrap modals and tooltips providing interactivity.
