        figure : bokeh.plotting.figure.Figure
            A Bokeh figure to plot.

        use_container_width : bool
            Whether to override the figure's native width with the width of
            the parent container. If ``use_container_width`` is ``True`` (default),
            Streamlit sets the width of the figure to match the width of the parent
            container. If ``use_container_width`` is ``False``, Streamlit sets the
            width of the chart to fit its contents according to the plotting library,
            up to the width of the parent container.
