This choropleth map visualizes renewable electricity share as a percentage of total electricity generation by country for 2022. Using a Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, it renders world countries from TopoJSON data, colored with a green-to-blue threshold scale. A hover tooltip displays each country’s name and its renewable share, with missing values marked as N/A. The visualization also includes graticules and a discretized legend, with data loaded from a linked CSV file.
