This example displays a geographic map of Uruguay using a Transverse Mercator projection, with the country filled in light green and a white sphere background. The map loads TopoJSON data from a GitHub gist and renders it as SVG paths via `d3.geoPath`. The visualization supports interactive zooming through `d3.zoom`, which applies a transform to the map group. Hovering over the country changes its fill to maroon, demonstrating user interaction with the geographic shapes.
