Data Tracking and Visualization


Health data

GPS Data

  • How to visualize?
  • Heat map?
  • Draw lines based on where I was?
  • I’m using Compass right now to track my location, as well as using Swarm to mark the places where I’ve been. Is it worth to use both tools? I guess it depends on the end goal.



  • Setup automatic collector.
  • Make visualization page like /books.
