This visualization displays a world map where each country is colored based on its primary balance data from a CSV file, with tooltips showing the country name, primary balance, economy type, and continent. The map uses a d3.geoEquirectangular projection with d3.geoPath to render TopoJSON world atlas data, and d3.zoom enables interactive panning and zooming. Countries are rendered as SVG paths that turn black on hover, while the primary balance values and regional metadata from the CSV are encoded in the title elements.
