title: How to plot a set of points in python?
body: <p>I have a set of points created through a python program which belongs to different clusters. I would like to plot it on a graph so that points in different clusters should be plotted with different colours.</p>
  
  <p>UPDATE</p>
  
  <p>In my case I have a univariate data ( marks of a test). Looking for a way to plot it. </p>
  
  <p>I have two clusters that are stored in two arrays. Like <code>x=[1,20,10,4]</code>, <code>y=[1644,34444]</code>. I would like to plot it like as in a cluster</p>
