 * 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,
 *            name: "Point2",
