Installing

If you use NPM, npm install d3-geo-polygon. Otherwise, download the latest release. You can also load directly from unpkg. AMD, CommonJS, and vanilla environments are supported. In vanilla, a d3 global is exported:

ipt src="https://unpkg.com/d3-geo@1"></script>
ipt src="https://unpkg.com/d3-geo-polygon@1"></script>
ipt>

projection = d3.geoEquirectangular()
.preclip(d3.geoClipPolygon({
  type: "Polygon",
  coordinates: [[[-10, -10], [-10, 10], [10, 10], [10, -10], [-10, -10]]]
}));
