Execute

1. Open a web browser and go to http://localhost:8000. This should load the GraphiQL interface.

2. In the query editor of GraphiQL, enter the following query

   query {
     users {
       id
       name
       posts {
         title
       }
     }
   }

3. After running the query in GraphiQL, expect to see a JSON response structured like this:

   {
     "data": {
       "users": [
         {
           "id": 1,
           "name": "Leanne Graham",
           "posts": [
             {
               "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit"
             }
             // Additional posts truncated for brevity
           ]
         },
         {
           "id": 2,
           "name": "Ervin Howell",
           "posts": [
             {
               "title": "et ea vero quia laudantium autem"
             },
             {
               "title": "in quibusdam tempore odit est dolorem"
             }
             // Additional posts truncated for brevity
           ]
         }
         // Additional users truncated for brevity
       ]
     }
   }

You can now add additional fields, and compose more queries together!
