Hi


 :A GraphQL query is a string that is sent to a server to be interpreted and fulfilled, which then returns JSON back to the client.


I want implementation of graphql using gremlin below

Without a sample graph, I'm using the modern graph...

graph = TinkerFactory.createModern()
g = graph.traversal()

g.V().has('name','marko').
    project('user','created','friends').
        by(valueMap(true,'name','age')).
        by(out('created').has('lang','java').valueMap('name')).
        by(out('knows').limit(5).valueMap(true,'name').fold())

[user:[id:1,label:person,name:[marko],age:[29]],
 created:[name:[lop]],
 friends:[[id:2,label:person,name:[vadas]],
        [id:4,label:person,name:[josh]]]]

This graph doesn't have anything like 'profilePicture' with 'size' so I used 'created' with 'lang' instead.
