This choropleth displays global unemployment rates by country using a green color scale, with data embedded directly in the code for 30 nations. Tooltips reveal country names and rates on hover. The map renders as SVG using `d3.geoPath` with a Natural Earth projection, `d3.geoGraticule` for latitude/longitude lines, and TopoJSON country boundaries. Built with React and D3 v7, the visualization loads world geometry and unemployment data as static objects.
