GraphQL Editor explorer allows to visually compose the query.
On the left side you have the file explorer - it helps to organize all the queries and mutations sets. Then when you create a new file - you can put mutations and queries there.
Just after the file explorer we have the GraphQL Query Language explorer. Here you can add queries, mutations and subscriptions.
After we add an operation we can use the visual explorer to create queries by clicking them out
It allows us to create queries using visual trees. Later on using the select with query names we can decide which query to execute.
