This data visualization is a choropleth map showing the number of music albums per country, rendered as an interactive SVG using D3 v5. The map uses a green color scale to represent album counts, and users can hover over countries to see details via a tooltip or click to open a modal with statistics. The code leverages D3’s `geoMercator` projection, `geoPath`, and `scaleLinear` for color mapping, and loads world map data from the `world-atlas` package alongside a local `data_map.json` file.
