This example displays a world map using a Hammer retroazimuthal projection, centered on parallel 52°N, with vector land and boundary outlines rendered as SVG paths clipped to the projected sphere. The code uses d3.geo.path with a custom projection and d3.geo.graticule to draw the graticule, while topojson.v1 loads and processes the world-50m GeoJSON data for land and country boundaries. A white stroke highlights the map boundary, and the projection’s clip angle ensures no artifacts appear beyond the map’s edge.
