This interactive map displays world countries with hover effects, highlighting each nation in red. The visualization uses the Natural Earth dataset for country boundaries, loaded from the world-atlas package via TSV and JSON files. Built with D3 v5, it employs geoNaturalEarth1 projection, geoPath for path generation, and the topojson feature function. The zoom interaction is implemented through d3's zoom and event modules, allowing users to pan and scale the map. Countries display names as tooltips by joining the TSV data with the geometry.
