This example presents an interactive world map built with React and D3, using the geoNaturalEarth1 projection and geoPath to render country boundaries from TopoJSON data loaded from the visionscarto-world-atlas. The map displays graticule lines and outlines, with countries colored according to a custom legend that maps percentage ranges to shades of red from the schemeReds palette. The visualization includes hover effects that change country fill colors, and a color legend component created with D3 selections to explain the color scale.
