This example visualizes the world’s countries as green filled regions with yellow borders projected on a black sphere, highlighting a natural Earth projection. The map renders geographic boundaries from the world-atlas 110m dataset using d3.geoPath with the geoNaturalEarth1 projection, while the topojson library converts TopoJSON features into GeoJSON. The SVG output displays all countries as static paths, with styling applied via CSS classes. The visualization demonstrates a straightforward choropleth-style map without interactivity, relying on D3’s geographic utilities and the bundled world-atlas source data.
