## voronoi

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

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

**Parameters**

-   `points` **[FeatureCollection][1]&lt;[Point][2]>** to find the Voronoi polygons around.
-   `options` **[Object][3]** Optional parameters (optional, default `{}`)
    -   `options.bbox` **[Array][4]&lt;[number][5]>** clipping rectangle, in [minX, minY, maxX, MaxY] order. (optional, default `[-180,-85,180,-85]`)

**Examples**

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

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

Returns **[FeatureCollection][1]&lt;[Polygon][6]>** a set of polygons, one per input point.
