This interactive world map shows country names as tooltips when hovering over each nation, and allows users to pan and zoom the projection. The visualization renders geographic data from the world-atlas TopoJSON and TSV files, using d3.geoPath with the Natural Earth projection. Interactions are enabled through d3.zoom, which applies transforms to the SVG group, while CSS hover states highlight countries in red. The code relies on d3.select, d3.event, and d3.json for data handling.
