This example displays an interactive world map with countries rendered as individual SVG paths, colored light green with black outlines, and highlighted in red on hover. It uses D3 v5's `geoNaturalEarth1` projection with `geoPath` to draw the map, and a light blue sphere for the oceans. Country boundaries come from the `world-atlas` package's countries-50m GeoJSON data, and the `topojson-client` library converts TopoJSON to GeoJSON for feature extraction. The chart supports zooming via D3's `zoom` event, which updates the SVG group transform in real-time.
