This example shows a stylized world map rendered as an SVG, displaying land masses in teal with country borders drawn as interior lines, overlaid on a light gray sphere with graticule grid lines. It uses the `geoNaturalEarth1` projection and `geoPath` from d3-geo, with geographic data loaded from the World Atlas TopoJSON file via `topojson.feature` and `topojson.mesh`. The visualization is built with React, managing the data-fetching lifecycle in a custom `useData` hook and rendering the final map through the `Marks` component.
