A world map rendered in SVG uses a blue sphere with green countries outlined in black, built with D3.js v5 and the topojson library. The code loads geographic data from the world-atlas 110m.json file, then applies a geoNaturalEarth1 projection via d3.geoPath to generate country paths. The visualization demonstrates a straightforward choropleth-like base map, with styling handled through CSS classes for the sphere and country boundaries.
