This example demonstrates how to create a world map using D3.js v5, rendering country boundaries as light green SVG paths on a blue sphere. It shows a natural Earth projection with subtle black stroke outlines for each country. The visualization loads GeoJSON data from the world-atlas TopoJSON file using `d3.json`, then converts it to geographic features with `topojson.feature`. The code applies `d3.geoPath` with a `geoNaturalEarth1` projection to draw both the sphere background and individual country shapes onto the SVG canvas.
