Using the GraphQL Interface
What is the Graphql Interface?
The graphql interface is a simple user interface that allows you to write queries and view the responses in real time.
Example of the interface
The interface allows you to write queries and click the play button to run them.
The results will be displayed on the right. 
You can also view documentation on what each of the queries do by using the docs sidebar on the side.
