Let's make a map with D3.js!
This example demonstrates a static world map using D3.js, rendering countries and the Earth’s sphere as SVG paths with a Natural Earth projection. It uses `d3.geoPath` with `d3.geoNaturalEarth1`, and the `topojson` library’s `feature` method to convert TopoJSON from the `world-atlas` dataset into GeoJSON features. The sphere is drawn in blue, countries in light green with black outlines, and the code loads data asynchronously via `d3.json`.
