This example displays a static world map using a Natural Earth projection, with countries rendered as filled green shapes with white borders. The visualization loads geographic data from the world-atlas package via `d3.json`, then converts it to GeoJSON features using the `feature` function from `topojson-client`. It draws the map with `d3.geoPath` and the `d3.geoNaturalEarth1` projection, positioning the map with scale and translate parameters. The SVG output is generated through D3's selection and append methods.
