This example displays a simple world map rendered with an equirectangular-like Natural Earth projection, including graticule and outline overlays. It uses d3.geoNaturalEarth1 and d3.geoPath to draw country boundaries as SVG paths, with data fetched from the visionscarto-world-atlas TopoJSON file and converted via topojson-client. The visualization fills the browser window and updates reactively through a state-driven render loop.
