This choropleth map visualizes global GDP per capita using a logarithmic color scale, with countries colored from dark to light based on economic output. Hovering over any country reveals a tooltip showing its name and exact GDP value. The visualization uses D3 v7 with `d3.geoNaturalEarth1` projection and `d3.geoPath` to render world geography from TopoJSON data, while `d3.scaleSequentialLog` with the Plasma interpolator handles color encoding. A graticule layer and interactive legend complete the SVG-based rendering.
