# new PolygonOverlay(points, options)

Creates a polygon overlay with an array of points and style options.

## Declaration

```data
constructor(
    points: CoordinateData[][] | CoordinateData[],
    options?: OverlayOptions,
);
```

## Parameters

- `points`: The points in the polygon as an array of arrays of doc://com.apple.mapkitjs/documentation/MapKitJS/Coordinate, or an array of doc://com.apple.mapkitjs/documentation/MapKitJS/Coordinate. For the latter, MapKit JS autowraps the array with an enclosing array.
