This interactive world map visualizes the Global Peace Index (GPI) 2023, coloring each country on a green-to-red gradient from safest to least safe. Hovering a country fades it slightly and displays a tooltip with its name and score. Built with D3 v7 and TopoJSON, the map uses `d3.geoPath` to render SVG country shapes, with a CSS-defined legend bar indicating the color scale.
