This interactive map visualization displays European countries with colored circles marking each nation's location. The circles are color-coded by musical genre preference, with a legend explaining the color scheme. Users can zoom and pan the map, and hovering over a circle reveals a tooltip showing the country name and its associated music genre. The visualization uses D3.js v6 with geoMercator and geoPath for the map projection, SVG circles for data points, and d3-scaleOrdinal for color assignment based on the countriesEuropean.json dataset.
