If bool, whether to draw a shadow beneath the pie. If dict, draw a shadow
            passing the properties in the dict to `.Shadow`.

            .. versionadded:: 3.8
                *shadow* can be a dict.

        startangle : float, default: 0 degrees
            The angle by which the start of the pie is rotated,
            counterclockwise from the x-axis.

        radius : float, default: 1
            The radius of the pie.

        counterclock : bool, default: True
            Specify fractions direction, clockwise or counterclockwise.

        wedgeprops : dict, default: None
            Dict of arguments passed to each `.patches.Wedge` of the pie.
            For example, ``wedgeprops = {'linewidth': 3}`` sets the width of
            the wedge border lines equal to 3. By default, ``clip_on=False``.
            When there is a conflict between these properties and other
            keywords, properties passed to *wedgeprops* take precedence.

        textprops : dict, default: None
            Dict of arguments to pass to the text objects.

        center : (float, float), default: (0, 0)
            The coordinates of the center of the chart.

        frame : bool, default: False
            Plot Axes frame with the chart if true.

        rotatelabels : bool, default: False
            Rotate each label to the angle of the corresponding slice if true.

        normalize : bool, default: True
            When *True*, always make a full pie by normalizing x so that
            ``sum(x) == 1``. *False* makes a partial pie if ``sum(x) <= 1``
            and raises a `ValueError` for ``sum(x) > 1``.

        data : indexable object, optional
            DATA_PARAMETER_PLACEHOLDER

        Returns
        -------
        patches : list
            A sequence of `matplotlib.patches.Wedge` instances

        texts : list
            A list of the label `.Text` instances.

        autotexts : list
            A list of `.Text` instances for the numeric labels. This will only
            be returned if the parameter *autopct* is not *None*.

        Notes
        -----
        The pie chart will probably look best if the figure and Axes are
        square, or the Axes aspect is equal.
        This method sets the aspect ratio of the axis to "equal".
        The Axes aspect ratio can be controlled with `.Axes.set_aspect`.
