This example displays a world map where each country is colored according to its economic category, using a sequential Blues color scheme. Hovering over a country highlights it in red and reveals a tooltip with its name and economy type. The map, built with D3.js, uses a Natural Earth projection and loads geographic data from the world-atlas package via TopoJSON, converting it to GeoJSON for rendering as SVG paths. Pan and zoom functionality is enabled through D3’s zoom utility.
