This interactive map visualizes world countries using a natural Earth projection, with hover highlighting and zoom controls. The visualization renders geographic boundaries as SVG paths, colored light green against a blue sphere, and displays country names as tooltips. It uses D3 v5's `geoNaturalEarth1` projection and `geoPath` for map generation, with data from the world-atlas package. The zoom functionality is implemented via D3's `zoom` event, while the `topojson` library's `feature` API processes the TopoJSON data.
