This choropleth map visualizes a socioeconomic metric across countries, using a spectral color scale to encode each nation's value from the provided CSV dataset. The map employs D3's `geoPath` and `geoNaturalEarth1` projection to render world country boundaries from the world-atlas TopoJSON, with a custom `colorLegend` showing the scale. Hovering highlights a country in red, and the visualization supports zooming via `d3.zoom`.
