This world map visualization displays a color-coded choropleth of country scores using a sequential red-yellow scale, with hover highlighting and a legend showing the score range. Built with D3 v5, it uses `geoNaturalEarth1` projection with `geoPath` to render the map, and `topojson` to load world geometry. Country data comes from a CSV file matched by ISO codes, and the visualization supports zoom and pan via D3's `zoom` behavior.
