This example shows a world map rendered as an SVG, with countries filled in light green and the ocean (sphere) in powder blue. It uses D3.js's `geoNaturalEarth1` projection and `geoPath` to convert geographic data into SVG path strings. The map data comes from the `world-atlas` package, loaded as TopoJSON and converted to GeoJSON using the `topojson.feature()` function. The `svg.append` and `selectAll` methods are used to draw the sphere and country paths onto the canvas.
