title: How to plot a filled polygon with coordinates on a map
body: <p>I am new to python and have just plotted my first map using matplotlib. I now want to plot a filled polygon or patch on this map using a set of coordinates I have. I have tried with pygame but it doesn't work. Do you have any suggestions? </p>
  
  <p>Thanks in advance</p>
  
  <pre><code># plot polygon using a set of coordinates        
  pygame.draw.polygon(map,brown,[[67.8942,9.8188],[68.0048,10.345],[68.7539,11.5195]],3)
  pygame.display.flip()
  </code></pre>
