This visualization displays renewable energy levels by country on a natural Earth projection map, with a color legend categorizing ordinal data. It uses d3.geoPath and d3.geoNaturalEarth1 to render world shapes, d3.scaleOrdinal with schemeSpectral for color mapping, and d3.zoom for panning. Data comes from a TSV file joined to TopoJSON world atlas geometries via d3.tsv and d3.json. Hovering highlights countries in red, and tooltips show country names and renewable values.
