I'm a newbie to Vega. Appreciate it if you can help me to build a visualizer on the aggregated results that I have as follows.  
For every `release`, I'd like to show the sum of duration per `workflow` (e.g., A, B, and C) based on the latest `id`.

Sample dataset:

```auto
release,id,workflow,sid,duration
1.0,1,A,x1,1
1.0,1,A,x2,6
1.0,2,A,x1,2
1.0,2,A,x2,3
1.0,1,B,y1,1
1.0,1,B,y2,2
1.0,2,B,y1,8
1.0,2,B,y2,3
1.0,3,B,y1,4
1.0,3,B,y2,2
1.1,1,A,x1,1
1.1,1,A,x2,6
1.1,2,A,x1,2
1.1,2,A,x2,4
1.2,1,C,y1,3
1.2,1,C,y2,2
1.2,2,C,y1,8
1.2,2,C,y2,3
1.2,4,C,y1,9
1.2,4,C,y2,7

```

Query:

```auto
GET discuss-duration/_search
{
  "size": 0,
  "aggs": {
    "workflow": {
      "terms": {
        "field": "workflow"
      },
      "aggs": {
        "ids": {
          "terms": {
            "field": "id",
            "order": { "max_id": "desc" },
            "size": 1
          },
          "aggs": {
            "max_id": {
              "max": {
                "field": "id"
              }
            },
            "sum_duration": {
              "sum": {
                "field": "duration"
              }
            }
          }
        }
      }
    }
  }
}

```

Results:

```auto
# Results

  "took": 1,
  "timed_out": false,

    "total": 1,
    "successful": 1,

                "sum_duration": {
                  "value": 6
                },
                "max_id": {
                  "value": 3
                }
              }
            ]
          }
        },
        {
          "key": "A",
          "doc_count": 4,
          "ids": {
            "doc_count_error_upper_bound": 0,
            "sum_other_doc_count": 2,
            "buckets": [
              {
                "key": 2,
                "doc_count": 2,
                "sum_duration": {
                  "value": 5
                },
                "max_id": {
                  "value": 2
                }
              }
            ]
          }
        }
      ]
    }
  }
}

I managed to create bar chart with Vega using the aggregated results.
