This example displays a world map using natural Earth projection, with countries filled in yellow and a light blue ocean outline. The map is rendered as SVG paths using D3's `geoNaturalEarth1` and `geoPath` APIs, with graticule lines and country borders shown in black. Hovering over a country reveals a tooltip with the country name. The geographic data comes from the VisionsCarto World Atlas TopoJSON dataset, loaded via the `topojson-client` library.
