    fig, ax = plt.subplots()
    
    x = np.arange(0, 2 * np.pi, 0.01)
    line, = ax.plot(x, np.sin(x))
    
    
    def animate(i):
        line.set_ydata(np.sin(x + i / 100))
        return line,
    
    
    def init():
        line.set_ydata(np.sin(x))
        return line,
    
    
    ani = animation.FuncAnimation(fig=fig, func=animate, frames=100,
                                  init_func=init, interval=20, blit=False)
