 * 1.  An array of arrays with 3 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.

 *         [2, 9, 2]
 *     ]
 *  ```
 *
 * 3.  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.scatter3d.turboThreshold), this option is not
 * available.
