This example displays a world map with countries filled in light green and oceans rendered in blue, using the Natural Earth 110m dataset loaded from the `world-atlas` package. It projects geographic coordinates with `d3.geoNaturalEarth1` and draws the sphere and country boundaries via `d3.geoPath`. The code uses the `topojson` library’s `feature` function to convert TopoJSON into GeoJSON features, then appends SVG paths to the canvas. Three.js is not used; all rendering occurs through SVG elements.
