GraphQL
========

`GraphQL <https://graphql.org/>`_ is a language for describing the
structure of data to be returned in an API.

.. note:: This generator will only create GraphQL definitions, it will
          not create runtime bindings.

Example Output
--------------

`personinfo.graphql <https://github.com/linkml/linkml/blob/main/examples/PersonSchema/personinfo/graphql/personinfo.graphql>`_

Overview

Graphql can be generated from a LinkML schema.

To run:
