/**
 * An array of data points for the series. For the `bubble` series type,
 * points can be given in the following ways:
 *
 * 1. An array of arrays with 3 or 2 values. In this case, the values correspond
 *    to `x,y,z`. If the first value is a string, it is applied as the name of
 *    the point, and the `x` value is inferred. The `x` value can also be
 *    omitted, in which case the inner arrays should be of length 2\. Then the
 *    `x` value is automatically calculated, either starting at 0 and
 *    incremented by 1, or from `pointStart` and `pointInterval` given in the
 *    series options.
 *    ```js
 *    data: [
 *        [0, 1, 2],
 *        [1, 5, 5],
 *        [2, 0, 2]
 *    ]
 *    ```
 *
 * 2. 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.bubble.turboThreshold), this option is not
 *    available.
 *    ```js
 *    data: [{
 *        x: 1,
 *        y: 1,
 *        z: 1,
 *        name: "Point2",
