This interactive map of the world renders country borders and landmasses in SVG using React and D3.js, drawing from the World Atlas TopoJSON dataset. The code applies a conic equidistant projection via `d3.geoConicEquidistant` and generates geographic paths with `d3.geoPath`, alongside graticules from `d3.geoGraticule`. The visualization layers a dark blue sphere for oceans, green land fills with darker strokes for interiors, and light cyan latitude/longitude lines, all styled through CSS classes within the `Marks` component.
