This interactive world map visualizes country boundaries and graticules, rendered as an SVG using React and D3 v5. The map is projected using d3.geoOrthographic, with land areas filled with a teal color and graticules drawn in light gray. The code uses d3.geoPath to project geographic features from the World Atlas TopoJSON, and d3.geoGraticule to generate the graticule lines. The map responds to mouse movement, though the visual effect of this interaction is not visible in the static display.
