This example presents a spinning globe, rendered as an orthographic projection that continuously rotates to showcase Earth's geography. The visualization uses d3-geo's `geoOrthographic` projection and `geoPath` to draw country outlines from TopoJSON data loaded from the visionscarto-world-atlas, along with a graticule and sphere outline. An animation is driven by `requestAnimationFrame`, which updates the projection's rotation state to create the spinning effect. The code is structured with a main module handling data fetching and state management, while a separate map module draws the geographic elements.
