title: Plot a scatter plot in python with matplotlib with dictionary
body: <p>I need help plotting a dictionary, below is the data sample data set. I want to create a scatter graph where x:y are (x,y) coordinates and title'x' would be the legend of the graph.. I want to create  graphs of below data set so combine all the below data in one graph. </p>
  
  <p>for example: plot title1':{x:y, x:y} in red( or any other color) make a legend(key) saying red(or whatever color) is for title1,</p>
  
  <p>do same for  title2:{x:y, x:y} (in a different color)....and so on.</p>
  
  <p>Any help would be greatly appreciated. Thank you.</p>
  
  <pre><code>data = {'title1':{x:y, x:y},title2:{x:y,x:y,x:y},'title3':{x:y,x:y}....}
  </code></pre>
  
  <p>I also followed this advise, but it was for individual graph.

  <p>This is what I have tried, i don't have much experience in matplotlib and couldn't find anything useful onlline. Any help would be greatly appreciated.</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import numpy as np
  d ={'5000cca234c1c445': {382877: 7, 382919: 3},

  '5000cca234c89421': {383173: 1, 383183: 2, 382917: 1, 382911: 1},

  '5000cca234c56488': {382909: 2, 382911: 5}}
  
  xval = []
  yval= []
  ttle = []
  print d
  for title, data_dict in d.iteritems():
     x = data_dict.keys()
     #print 'title is', title
     #print 'printing x values',x   
     xval = xval + x
     print xval
     y = data_dict.values()
     yval = yval+y
     ttle.append(title)
     print  yval
  #print 'printing y values', y         
  #plt.figure()
  print xval
  print yval
  print ttle
  plt.scatter(xval,yval)
  plt.show()
