This colorpleth map visualizes a global economic dataset, showing each country colored according to its value on a spectral scale. The map uses D3 v5 and the `geoNaturalEarth1` projection to render geographic boundaries, with an ordinal color scale and an interactive legend built through `scaleOrdinal` and custom SVG elements. The choropleth overlays data from the World Atlas TopoJSON and TSV files onto a natural Earth sphere, with zoom functionality and hover effects highlighting individual countries.
