This example displays a choropleth-style world map rendered with the Natural Earth projection using d3.geoNaturalEarth1 and d3.geoPath. The visualization shows land masses filled in blue, a pale sphere background, graticule lines, and black interior borders between countries, all drawn as SVG paths. The code loads GeoJSON and TopoJSON data from the world-atlas package via d3.json and topojson.feature/mesh, with React managing the component state and rendering. A Google Fonts Poppins stylesheet complements the map’s simple color scheme.
