This example presents a world map using the Natural Earth projection. It renders continents as light green shapes with subtle black borders against a blue spherical backdrop, showing the capabilities of D3.js for geospatial visualization. The code loads GeoJSON data from the `world-atlas` package and processes it with `topojson`'s `feature` function before projecting it using `d3.geoNaturalEarth1` and `d3.geoPath`. The visualization is drawn as SVG paths, with the sphere and country elements styled via CSS classes.
