## voronoi

Takes a collection of points and a bounding box, and returns a collection
of Voronoi polygons.

The Voronoi algorithim used comes from the d3-voronoi package.

### Parameters

*   `points` **[FeatureCollection][1]<[Point][2]>** points around which to calculate the Voronoi polygons
*   `options` **[Object][3]** Optional parameters (optional, default `{}`)

    *   `options.bbox` **[BBox][4]** clipping rectangle, in \[minX, minY, maxX, MaxY] order (optional, default `[-180,-85,180,-85]`)

### Examples

```javascript
const options = {
  bbox: [-70, 40, -60, 60]
};
const points = turf.randomPoint(100, options);
const voronoiPolygons = turf.voronoi(points, options);

//addToMap
const addToMap = [voronoiPolygons, points];
```

Returns **[FeatureCollection][1]<[Polygon][5]>** a set of polygons, one per input point
