A world map colored by each country's economic status, rendered with SVG paths via d3.geoPath and a geoEquirectangular projection. Hovering reveals a tooltip with the country name, primary balance, and broader economic classification. The color legend, built with a custom colorLegend function, uses an ordinal scale mapped to the d3 schemeSpectral range. Data comes from a CSV joined with TopoJSON world-atlas shapes, while d3.zoom enables panning and zooming.
