+```html
+<script type="module">
+import {geoDelaunay} from "https://cdn.skypack.dev/d3-geo-voronoi@2";

+
+For legacy environments, you can load d3-geo-voronoi’s UMD bundle from an npm-based CDN such as jsDelivr; a `d3` global is exported:

 This API is a similar to [d3-delaunay](https://github.com/d3/d3-delaunay)’s API. It provides information on the Delaunay triangulation (edges, triangles, neighbors, Voronoi cells, etc) as indices in two arrays — the array of points, and the array of circumcenters. It facilitates topological computations. To draw the actual triangles, Voronoi cells etc, the [Voronoi](#Voronoi) API described in the next section will often be easier to use.
