https://dgraph.io/downloads -- to Install GraphQL (I used the linux installation, there is a startup script for that in a file called startup.sh, but the Docker installation should work fine)
curl.txt -- Curl example that I had created from trial and error. This really should have been in their documentation. Hopefully this will help you out.
http_api.rs -- Started making some http calls.
main.rs -- For running the API calls.
*.schema -- Target files for HTTP calls (look at .txt files for example of use). Do not think this will be the final way to do things but it works for now.
