Let's make a map with D3.js!
This D3.js example displays a natural Earth projection map of the world, with countries colored by their economic classification using a spectral color scale and an interactive color legend. The visualization loads geographic and metadata from the world-atlas dataset via TopoJSON, then renders each country as an SVG path. The map supports zooming through d3.zoom, and hovering over a country highlights it in red while a tooltip shows its name and economy type.
