This interactive map of the world renders countries as green SVG paths with hover highlighting in red. It loads GeoJSON from the world-atlas TopoJSON dataset and country names from a TSV file, then joins them by ISO numeric code to display each country’s economy type as a tooltip on hover. The map uses the `geoNaturalEarth2` projection and `geoPath` from d3-geo-projection, and supports pan and zoom through d3’s `zoom` behavior applied to the SVG group.
