This rotating globe visualization uses an orthographic projection to display world country polygons, a graticule grid, and three labeled city points (Munich, San Antonio, and Melbourne). The globe continuously rotates via a d3.timer, updating the country paths, graticule lines, city markers, and labels each frame. Labels are hidden when their corresponding city is on the far side of the globe, determined by the great-arc distance from the map’s center. The example uses d3.v3 with SVG and animation, loading TopoJSON world data and styling countries, graticules, and points with distinct colors.
