    Takes a bounding box and the diameter of the cell and returns a FeatureCollection of flat-topped hexagons or triangles (Polygon features) aligned in an "odd-q" vertical grid as described in Hexagonal Grids.


    • bbox BBox extent in [minX, minY, maxX, maxY] order
    • cellSide number 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 Optional parameters (optional, default {})
      • options.units string used in calculating cell size, can be degrees, radians, miles, or kilometers (optional, default 'kilometers')
      • options.properties Object passed to each hexagon or triangle of the grid (optional, default {})
      • options.mask Feature<Polygon>? if passed a Polygon or MultiPolygon, the grid Points will be created only inside it
      • options.triangles boolean whether to return as triangles instead of hexagons (optional, default false)


    var bbox = [-96,31,-84,40];
    var cellSide = 50;
    var options = {units: 'miles'};
    var hexgrid = turf.hexGrid(bbox, cellSide, options);
    var addToMap = [hexgrid];

    Returns FeatureCollection<Polygon> a hexagonal grid
