This example renders a global map with an orthographic projection, displaying landmasses in teal, country borders as fine gray lines, and a graticule overlay on a light sphere. The visualization uses D3’s `geoOrthographic` and `geoPath` to project and draw geographic features, while TopoJSON’s `feature` and `mesh` extract land polygons and country boundaries from the world-atlas dataset. The React-based code structure separates data handling in `useData` from the SVG marks rendered by the `Marks` component, with styling applied via CSS classes.
