This example displays a world map using an equal-earth projection on an SVG canvas. The visualization renders ocean and landmasses as distinct shaded regions, with country boundaries outlined in black. The code loads geographic data from the World Atlas TopoJSON dataset and converts it to GeoJSON using the `feature` function from topojson. It relies on d3’s `geoEqualEarth` projection and `geoPath` to draw the sphere and country shapes.
