Zoom and Rotating (Reprojecting)
This example shows a continuously rotating and reprojecting world map rendered onto a canvas texture inside a 3D A-Frame scene. It demonstrates how geographic data can be integrated with WebVR-style environments, drawing country polygons, graticules, and the sphere outline using D3 v4’s `d3.geoMercator` projection, `d3.geoPath`, and `d3.geoGraticule`. The animation runs via `d3.timer`, updating the projection rotation each frame and clearing/redrawing the canvas context. The map uses GeoJSON world land data loaded from `land.geojson` and displays alongside a simple A-Frame box primitive.
