        width = 100
        height = 50
        x = 10
        y = 10

            value=Intensity(88),
            style_name=FamilyGraphics.DEFAULT_DRAWING_STYLE,
            style_family=DrawStyleFamilyKind.GRAPHICS,
        )

        doc.close_doc()
    return 0

    raise SystemExit(main())

Running the above code will produce the following results in the Draw dialog.
