This interactive map of the world displays country names as tooltips on hover, with countries highlighted in red. Users can pan and zoom the map using mouse interactions. Built with d3.js, the visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to render SVG paths from TopoJSON data sourced from world-atlas, and `d3.zoom` for panning and zooming. The country names come from a TSV file, and hover effects are handled through CSS.
