GraphQL is a very popular API layer that, while it often uses JSON as a transport, and that can be used to display the result atleast somewhat formatted, due to the extra inforamtion in the response, it is very difficult to parse. Information will be duplicated, being displayed both after the key, and indented as another layer. (this is a problem with existing JSON parsing as well IMO)
There are already extensions to assist with developing GQL, however, integrating into the networking tab will allow much closer debugging to the active site functionality, and allow seeing with much more ease what specific requests are being made, or what specific responses are being returned.
