        radius: Radius for the circular or square boundary. Defaults to None.
        dilate: Amount to dilate the boundary. Defaults to None.
        save_as: Path to save the resulting plot. Defaults to None.

        constrained_layout: Whether to use constrained layout for the figure. Defaults to True.
        credit: Parameters for the credit message. Defaults to an empty dictionary.
        mode: Mode for plotting ('matplotlib' or 'plotter'). Defaults to "matplotlib".
        multiplot: Whether to use multiplot mode. Defaults to False.
        show: Whether to display the plot using matplotlib. Defaults to True.
        x: Translation parameter in the x direction. Defaults to 0.
        y: Translation parameter in the y direction. Defaults to 0.
        scale_x: Scaling parameter in the x direction. Defaults to 1.
        scale_y: Scaling parameter in the y direction. Defaults to 1.
