title: Python:Plot scipy plot on top of voronoi diagram
body: <p>I am trying to plot on top of scipy plot. Used [this solution] (<a href="https://stackoverflow.com/questions/45997002/python-plot-on-top-of-scipy-plot-voronoi/63181344#63181344">Python: plot on top of scipy plot? (voronoi)</a>) but still cannot get single plot. Can anyone help? Thanks in advance...
  Sample plots are the following and trying to overlap them: <a href="https://i.stack.imgur.com/d1zLN.png" rel="nofollow noreferrer">Voronoi Diagram</a> and <a href="https://i.stack.imgur.com/Pq8bv.png" rel="nofollow noreferrer">Scatter Plot</a></p>
  <pre><code>vor = Voronoi( points )
  voronoi_plot_2d(vor)
  
  import matplotlib.pyplot as plt
  import csv
  x = []
  y = []
  
  with open('Junctions.csv','r') as csvfile:
      plots = csv.reader(csvfile, delimiter=',')
      for row in plots:
          x.append((row[0]))
          y.append((row[1]))
  
  fig,ax = plt.subplots()
  ax.scatter(x,y,s=5,color='r')
  
  for i, txt in enumerate(n):
      ax.annotate(txt, (x[i], y[i]), size = 6)
  
  plt.show()
  </code></pre>
