title: Datamaps JS Dynamically get data from json file at regular intervals
body: <p>I want to be able to create a dynamic threat map to display the cyber attacks. I'm able to create the map and display all the co-ordinates directly but how do I achieve it dynamically ?</p>

  <li>How to dynamically fetch from file containing the json data</li>
  <li>Which service to use for dynamic plotting the arcs on the map</li>
  <li>Should I use socket.io for real time programming in order to enter the data into the database simultaneously ? </li>
  </ol>
  
  <p>I'm trying to achieve something like this : <a href="https://threatmap.checkpoint.com/ThreatPortal/livemap.html" rel="nofollow noreferrer">https://threatmap.checkpoint.com/ThreatPortal/livemap.html</a></p>
  
  <p>Any help appreciated. Thank you!</p>
