        Parameters
        ----------
        angle
            The angle of rotation in radians. Predefined constants such as ``DEGREES``
            can also be used to specify the angle in degrees.
        axis
            The rotation axis (see :class:`~.Rotating` for more).
        about_point
            The point about which the mobject rotates. If ``None``, rotation occurs around
            the center of the mobject.
        about_edge
            The edge about which to apply the scaling.

        Returns
        -------
        :class:`Mobject`
            ``self`` (for method chaining)


        .. note::
            To animate a rotation, use :class:`~.Rotating` or :class:`~.Rotate`
            instead of ``.animate.rotate(...)``.
            The ``.animate.rotate(...)`` syntax only applies a transformation
            from the initial state to the final rotated state
            (interpolation between the two states), without showing proper rotational motion
            based on the angle (from 0 to the given angle).
