It's programatic system, you just fork, edit index page to your needs and deploy your own version. Maybe future releases will introduce some admin area for managing that stuff, but so far it's only MVP release after one-weekend rumble :)
Graphing is made with d3 and geo extension - learning how to use it was one of my goals for this app, it looks nice so far but doesn't have all features i wanted to implement, though.
Deployment isn't that complex, app is prepared for heroku and actually goes with few commands:
Easy peasy! Development is super easy as well as there's configured Vagrant box available.
In case of frontend, it's disabled for this demo to prevent users from posting their emails - admin area contains only dummy auto-generated data. If you install the app on your own it will show proper, working front page.
