Как сделать анимацию движения объекта по кругу?

#Importing required libraries
%matplotlib notebook
import matplotlib.pyplot as plt
import numpy as np
from celluloid import Camera
import ffmpeg
 
 
#Creating Data
x = np.linspace(0, 10, 100)
 
#defining a function to return sine of input values.
def fun(i):
    y = np.sin(i)
    return y
 
x_y = fun(x)
 
#Creating matplotlib figure and camera object
fig = plt.figure()
plt.xlim(0,10)
plt.ylim(-2,2)
camera = Camera(fig)
 
#Looping the data and capturing frame at each iteration
for i in x:
    plt.plot(x,x_y , color = 'green' , lw = 0.8)
    f = plt.scatter(i, fun(i) , color = 'red' , s = 200)
    plt.title('tracing a sin function')
    camera.snap()
 
#Creating the animation from captured frames
animation = camera.animate(interval = 200, repeat = True,
                           repeat_delay = 500)
