This choropleth map shows the primary balance as a percentage of GDP for 55 countries, with a color legend that filters the map when a value is clicked, dimming non-matching countries. The visualization uses d3.geoEquirectangular for the projection and d3.geoPath to render the world map, with d3.zoom enabling pan and zoom interaction. Data is loaded via d3.csv and d3.tsv from the IMF website, and the ordinal color scale uses d3.schemeYlOrRd. The map is rendered as SVG, with hover highlighting and click-based filtering managed through D3 selections.
