 var polyline = draw.polyline([[0,0], [100,50], [50,100]]).fill('none').stroke({ width: 1 })

+Polylines can be updated using the `plot()` method:

+polyline.plot([[0,0], [100,50], [50,100], [150,50], [200,50]])

 ### Polygon
 The polygon element, unlike the polyline element, defines a closed shape consisting of a set of connected straight line segments:
