    Args:
        host: endpoint for the database instance
        port: port number for the database instance, default is 8182
        use_https: whether to use secure connection, default is True
        client: optional boto3 Neptune client
        credentials_profile_name: optional AWS profile name
        region_name: optional AWS region, e.g., us-west-2
        service: optional service name, default is neptunedata
        sign: optional, whether to sign the request payload, default is True

    Example:
        .. code-block:: python

        graph = NeptuneGraph(
            host='<my-cluster>',
            port=8182
        )

    *Security note*: Make sure that the database connection uses credentials
        that are narrowly-scoped to only include necessary permissions.
        Failure to do so may result in data corruption or loss, since the calling
        code may attempt commands that would result in deletion, mutation
        of data if appropriately prompted or reading sensitive data if such
        data is present in the database.
        The best way to guard against such negative outcomes is to (as appropriate)
        limit the permissions granted to the credentials used with this tool.

        See https://python.langchain.com/docs/security for more information.
