create a program to represent how a given code is working in graphical form

def graph_function(function, x_range):
  xs = list(x_range)
  ys = []
  for x in xs:
    ys.append(function(x))
  import matplotlib.pyplot as plt
  plt.plot(xs,ys)
  plt.show()
    
graph_function(lambda x: x**2, range(-100, 100))
