title: JSON Schema to GraphQL schema converters
body: <p>Are there any adapters which are converting JSON Schema schemas (e.g from Swagger) to GraphQL schemas?
  There is even an official article about wrapping around REST <a href="http://graphql.org/blog/rest-api-graphql-wrapper/" rel="noreferrer">http://graphql.org/blog/rest-api-graphql-wrapper/</a>, but usually REST already described and Swagger is the most popular format for it.
  Wouldn't like to write it by my own if there is already existing implementation.</p>
