An example of a GraphQL schema and query with `caliban`:
```scala
import caliban.GraphQL.graphQL
import caliban.RootResolver

case class Character(name: String, age: Int)

def getCharacters(): List[Character] = ???

// schema
case class Queries(characters: List[Character])

// resolver
val queries = Queries(getCharacters)
import caliban.GraphQL.graphQL
import caliban.RootResolver

val api = graphQL(RootResolver(queries))

for {
interpreter <- api.interpreter
} yield interpreter
case class GraphQLResponse[+E](data: ResponseValue, errors: List[E])
val query = """
{
characters {
name
}
}"""
for {
result <- interpreter.execute(query)
_ <- zio.console.putStrLn(result.data.toString)
} yield ()
result <- interpreter.execute("{ characters { name } }")
} yield result
```
