This example displays a spherical projection of Africa using the Chamberlin Africa projection, with country boundaries rendered as SVG paths. Hovering over a country highlights it in orange, and users can pan and zoom the map via d3.zoom. The visualization uses d3.geoPath and topojson.feature to draw countries from World Atlas TopoJSON data, with country names loaded from a TSV file and shown as tooltips. The code imports d3-geo-projection for the projection and applies zoom transforms to a grouped SVG element.
