This interactive map displays world countries from the World Atlas TopoJSON and TSV data. It supports pan and zoom via the d3.zoom API. Users can hover over a country to reveal its name label, which is positioned using d3.geoPath centroids. Clicking a country triggers a box zoom to its bounds. The map is rendered using the d3.geoNaturalEarth1 projection, with country labels toggled on mouseover and click events.
