The Spline annotation is used to draw cubic Bezier curves. In the overlay below, the spline is in green and the control points are shown by the light grey line:

points = [(-0.3, -0.3), (0,0), (0.25, -0.25), (0.3, 0.3)]
overlay = hv.Spline((points,[])) * hv.Curve(points)
overlay.opts(
    opts.Curve(color='#D3D3D3'), 
    opts.Spline(color='green', line_width=6))

Note that the Bokeh Spline does not support the same control codes as the matplotlib version which is why the codes are supplied above as an empty list.

For full documentation and the available style and plot options, use hv.help(hv.Spline).
