This visualization displays a world map using an equirectangular projection, with countries rendered as yellow filled paths with black strokes. The map is interactive, as hovering over a country highlights it in red. Built with D3.js v5 and TopoJSON, it uses `d3.geoPath` and `d3.geoEquirectangular` to project geographic data from the world-atlas countries-110m.json file into SVG paths. The background sphere is styled with a blue fill, and the countries are drawn as separate SVG path elements.
