* axis, setting the `jitter.x` to 0.24 will render the point in a
* random position between 0.24 units to the left and 0.24 units to the
* right of the true axis position. On a category axis, setting it to
* 0.5 will fill up the bin and make the data appear continuous.
*
* When rendered on top of a box plot or a column series, a jitter value
* of 0.24 will correspond to the underlying series' default
* [groupPadding](

* calculated, either starting at 0 and incremented by 1, or from

* 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, 0],
* [1, 8],
* [2, 9]
* ]
* ```
*
* 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.scatter.turboThreshold), this option is not
* available.
