This visualization displays a world map using an orthographic projection, depicting the globe with blue oceans, green landmasses, and a graticule grid. Built with d3.geoOrthographic and d3.geoPath, it renders country boundaries from the Visionscarto World Atlas TopoJSON data, styled with green fills and white strokes. The map loads data asynchronously via fetch and topojson-client, then draws graticule lines, an outline, and country paths onto an SVG canvas.
