values = [(300,0), (150,150), (0,300)]
curve_widget = CurveWidget(root, values, line_color="purple",
point_color="white", outline="black")
curve_widget.pack(side="left", padx=10, pady=10)
values2 = [(300,0), (150,150), (0,300)]
curve_widget2 = CurveWidget(root, values2)
curve_widget2.pack(side="left", padx=10, pady=10)
