         * An array of data points for the series. For the `streamgraph` series type,
         * points can be given in the following ways:
         *
         * 1. An array of numerical values. In this case, the numerical values will be
         *    interpreted as `y` options. The `x` values will be automatically
         *    calculated, either starting at 0 and incremented by 1, or from
         *    `pointStart` and `pointInterval` given in the series options. If the axis
         *    has categories, these will be used. Example:
         *    ```js
         *    data: [0, 5, 3, 5]
         *    ```
         *
         * 2. An array of arrays with 2 values. In this case, the values correspond to
         *    `x,y`. If the first value is a string, it is applied as the name of the
         *    point, and the `x` value is inferred.
         *    ```js
         *        data: [
         *            [0, 9],
         *            [1, 7],
         *            [2, 6]
         *        ]
         *    ```
         *
         * 3. An array of objects with named values. The following snippet shows only a
         *    few settings, see the complete options set below. If the total number of
         *    data points exceeds the series'
         *    [turboThreshold](#series.area.turboThreshold),
         *    this option is not available.
         *    ```js
         *        data: [{
         *            x: 1,
         *            y: 9,
