you notice any issues during this transition or have suggestions, please
let us know.
- queries: used to find a starting point and traverse a subgraph

Introspection
Many GraphQL tools support introspection and generate documentation to help you explore an API. There are several tools in the GraphQL ecosystem you can use to explore an API, including GraphQL Playground, Insomnia, GraphiQL, Postman, and Altair. You can also explore your GraphQL API using the API explorer thatâs included in the Dgraph Cloud web UI. Navigate to the GraphQL tab where you can access the introspected schema from the âDocumentation Explorerâ in the right menu.
