I am getting this error

```auto
Invalid specification {...}
Make sure the specification includes at least one of the following properties: "mark", "layer", "facet", "hconcat", "vconcat", "concat", or "repeat"

```

I was using the pie chart from the github examples and using the kibana sample data logs. I made a range query for the last 90 days and an agg for doc count of the source and destination doc counts by terms.  
I tried to convert the pie chart that works from the github examples for vega but as a newbie to vega I am missing something here, since a relative 1 for 1 swap between example and test does not work:

```auto

  ],

              lte: "now"

          }
        },
        aggs: {
          test: {
            terms: {

              order: {
                "_key": "asc"
              }
            }
          }
        }
      }
    }
  },

      sort: {signal: "sort"}
    }
  ],

  scales: [

  ],

      encode: {

          x: {signal: "width / 2"},
          y: {signal: "height / 2"}
        },
        update: {
          startAngle: {field: "startAngle"},
          endAngle: {field: "endAngle"},
          padAngle: {signal: "padAngle"},
          innerRadius: {signal: "innerRadius"},
          outerRadius: {signal: "width / 2"},
          cornerRadius: {signal: "cornerRadius"}
        }
      }
