This example shows a dynamic globe where glowing arcs trace flight paths between cities across the world. It uses D3’s force simulation to position the nodes on the sphere and Canvas’s `getImageData` to render the points and curved paths. The visualization rotates the globe continuously via `d3.timer` while the arcs animate along their routes. The underlying geographic data is drawn with `d3.geoPath` and a Natural Earth projection, all rendered on a single `<canvas>` element.
