To mitigate the risk of circular references in GraphQL, you can follow these recommendations:
1. **Depth Limiting**:
Implement a middleware to check the depth of the query, and raise an error if it exceeds the limit.
Example:
=== "python"
	```python
    class DepthAnalysisMiddleware:
        def resolve(self, next, root, info, **args):
            if info.operation.selection_set:
                depth = 0
                for field in info.operation.selection_set.selections:
                    depth = max(depth, self._get_depth(field))
                if depth > 3:
                    raise Exception('Query depth is too high')
            return next(root, info, **args)
    
        def _get_depth(self, field):
            if field.selection_set:
                return 1 + max(self._get_depth(f) for f in field.selection_set.selections)
            return 1
	```


2. **Circular Reference Detection**:
Redesign the schema to avoid circular references.
Example of Circular Reference:
=== "python"
	```python
    class User(graphene.ObjectType):
        id = graphene.ID()
        name = graphene.String()
        friends = graphene.List(lambda: User)
        
        def resolve_friends(self, info):
            return [User(id=1, name='Alice'), User(id=2, name='Bob')]
	```

Example of redesigned Schema:
=== "python"
  ```python
    class FriendProfile(graphene.ObjectType):
        id = graphene.ID()
        name = graphene.String()
    
    class User(graphene.ObjectType):
        id = graphene.ID()
        name = graphene.String()
        friends = graphene.List(FriendProfile)
        
        def resolve_friends(self, info):
            return [FriendProfile(id=1, name='Alice'), FriendProfile(id=2, name='Bob')]
  ```


=== "JavaScript"
  ```javascript
        const FriendProfile = new GraphQLObjectType({
            name: 'FriendProfile',
            fields: {
                id: { type: GraphQLID },
                name: { type: GraphQLString }
            }
        });
        
        const User = new GraphQLObjectType({
            name: 'User',
            fields: {
                id: { type: GraphQLID },
                name: { type: GraphQLString },
                friends: { type: new GraphQLList(FriendProfile) }
            }
        });  
  ```
