Online demo not working

[mnlbox]

Hi guys,
I try to see the online demo but its freeze in Please wait comment. Also when I try to open GraphiQL app it's also returning this error:
TypeError: NetworkError when attempting to fetch resource.

Same thing for me. Also all of the "View source" links are broken. It looks like after the repository was moved here, nobody went back to check that everything was working correctly.

@wawhal The demo looks like it would be totally awesome if it worked. I'm sure with a tiny bit of effort you could have it working again :)
