This choropleth shows a world map with countries colored by their Pasta Variety Index, a higher value indicating more varieties. Hovering reveals each country’s value via a tooltip. Built with D3 v7 and TopoJSON, it uses `d3.geoMercator` and `d3.geoPath` to project the 110m country outlines, with a sequential `YlOrRd` color scale mapping values from 4 to 13. The map fetches world-atlas data asynchronously and renders to SVG.
