    "``Scatter3D`` represents three-dimensional coordinates which may be colormapped or scaled in size according to a value. They are therefore very similar to [``Points``](Points.ipynb) and [``Scatter``](Scatter.ipynb) types but have one additional coordinate dimension. Like other 3D elements the camera angle can be controlled using ``azimuth``, ``elevation`` and ``distance`` plot options:"
