This example presents an interactive world map using a natural Earth projection, with countries colored light green and the sphere filled blue. Hovering over a country turns it red and reveals its name via a tooltip, while users can zoom and pan by dragging. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` for rendering the map, and `d3.zoom` for interaction. It loads geographic data from the world-atlas package (JSON and TSV files) and leverages the TopoJSON library to convert topology into features.
