+## hexGrid
+
+Takes a bounding box and the diameter of the cell and returns a [FeatureCollection][1] of flat-topped
+hexagons or triangles ([Polygon][2] features) aligned in an "odd-q" vertical grid as
+described in [Hexagonal Grids][3].
+
+**Parameters**
+
+-   `bbox` **[BBox][4]** extent in [minX, minY, maxX, maxY] order
+-   `cellSide` **[number][5]** length of the side of the the hexagons or triangles, in units. It will also coincide with the
+    radius of the circumcircle of the hexagons.
+-   `options` **[Object][6]** Optional parameters (optional, default `{}`)
+    -   `options.units` **[string][7]** used in calculating cell size, can be degrees, radians, miles, or kilometers (optional, default `'kilometers'`)
+    -   `options.properties` **[Object][6]** passed to each hexagon or triangle of the grid (optional, default `{}`)
+    -   `options.mask` **[Feature][8]&lt;[Polygon][9]>?** if passed a Polygon or MultiPolygon, the grid Points will be created only inside it
+    -   `options.triangles` **[boolean][10]** whether to return as triangles instead of hexagons (optional, default `false`)
+
+**Examples**
+
+```javascript
+var bbox = [-96,31,-84,40];
+var cellSide = 50;
+var options = {units: 'miles'};
+
+var hexgrid = turf.hexGrid(bbox, cellSide, options);
+
+//addToMap
+var addToMap = [hexgrid];
+```
+
+Returns **[FeatureCollection][11]&lt;[Polygon][9]>** a hexagonal grid
