This example displays a world map constructed from country boundary data. The visualization renders the geographic outlines as a series of black paths, with each path representing a distinct country. The React application loads the world-atlas dataset from the unpkg CDN and processes it using topojson’s feature function. The map is rendered as a static SVG using the d3.line function with natural curve interpolation applied to the coordinate data. No interactivity or additional styling is applied beyond the base strokes.
