This interactive dashboard visualizes global music data through a choropleth map. Users click a country to see its total album count and select from three additional charts: a bar chart of top genres, a lollipop chart of popular artists, and a line chart of albums per year. The map uses d3.geoPath with TopoJSON and Mercator projection, while the detail charts employ d3.scaleBand, d3.scaleLinear, and d3.scaleTime. Colors encode album counts via a linear scale, and tooltips display hover details across all views.
