This visualization shows a world map where each country is colored according to its economic status, using a diverging red-yellow-green color scale derived from a dataset of primary balance values. The map supports zooming via d3.zoom, and a color legend generated with custom D3 code displays the ordinal scale’s categories. The geographic paths are rendered using d3.geoPath with a geoEquirectangular projection, while country data is loaded from a CSV file merged with TopoJSON world atlas geometry using topojson.feature.
