This example shows a world map rendered as an SVG, with countries filled in light green and oceans in blue. It uses D3.js version 5 and the `d3.geoPath` API with a Natural Earth projection to generate the map geometry. Geographic data comes from the world-atlas package, loaded via `d3.json`. The code also includes a sphere outline for the globe and uses the topojson library’s `feature` function to convert the raw data into usable features.
