This interactive map displays world countries colored in light green against a blue ocean, with hover effects highlighting each country in red. The visualization uses a natural Earth projection realized through d3.geoPath and d3.geoNaturalEarth1, rendering geographic data from the world-atlas TopoJSON dataset alongside names from its accompanying TSV file. Users can pan and zoom the map using d3.zoom, which applies transformations to the entire group of country paths. Tooltips showing country names appear via SVG title elements appended to each path.
