Examples for both queries:

// graphql
query MyQuery {
  allPageViews(sort: {order: DESC, fields: totalCount}) {
    nodes {
      id
      totalCount
    }
  }
}

// returns
{
  "data": {
    "allPageViews": {
      "nodes": [
        {
          "id": "/",
          "totalCount": 703
        },
        {
          "id": "/how-to-set-up-gatsby-typescript-eslint-prettier/",
          "totalCount": 126
        },
        {
          "id": "/react-hooks-vs-redux/",
          "totalCount": 121
        },
      ],
    },
  },
}

// graphql
query MyQuery {
  pageViews(id: {eq: "/how-to-set-up-gatsby-typescript-eslint-prettier/"}) {
    id
    totalCount
  }
}

// returns
