title: Heat Map Python
body: <p>I am trying to plot a heat map. The data that I use has Geo coordinates and time in seconds. The nature of data is edges encounter each other at certain geo location and spend some time connected. Considering the geo location and the time those edges are connected to each other I need to plot a heat map. </p>
  
  <p>The edges are connected to each other and they happen to be connected for certain amount of time in seconds and at that time they are in certain geo location. I need to plot a heat map to identify the crowd density and the time spent in that location. </p>
  
  <p><code>col[0]</code> and <code>col[1]</code> are edges <code>col[2]</code> time connected <code>col[3]</code> to <code>col[7]</code> are the geo coordinates.</p>
