This example displays a simple world map with country boundaries rendered in blue, using a Natural Earth projection with graticule lines and an outline. It loads GeoJSON data from the visionscarto-world-atlas package via a fetch request and converts TopoJSON using topojson-client. The visualization uses d3.geoPath and d3.geoNaturalEarth1 to project and draw the map, with countries filled in blue and stroked in white. The state management handles asynchronous data loading through a loader pattern.
