This example displays an interactive world map using an equirectangular projection, with countries rendered as SVG paths filled in turquoise and outlined in black. Hovering over any country highlights it in red. Built with D3.js v5 and TopoJSON, it uses `d3.geoEquirectangular` and `d3.geoPath` to generate the geometry, and loads geographic data from the world-atlas countries-110m.json file via `d3.json`.
