 * 1. An array of arrays with 3 or 2 values. In this case, the values correspond

 *    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, 9, 7],
 *        [1, 10, 4],
 *        [2, 6, 3]
 *    ]
 *    ```
 *
 * 2. An array of objects with named values. The objects are point configuration
 *    objects as seen below. If the total number of data points exceeds the
 *    series' [turboThreshold](#series.tilemap.turboThreshold), this option is
 *    not available.
 *    ```js
 *    data: [{
 *        x: 1,
 *        y: 3,
 *        value: 10,
 *        name: "Point2",
