 * 1. The array of arrays, with `keys` property, which defines how the fields in
 *     array should be interpreted
 *    ```js
 *       keys: ['id', 'parent'],
 *       data: [
 *           ['Category1'],
 *           ['Category1', 'Category2']
 *       ]
 *
 * 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.area.turboThreshold),
 *    this option is not available.
 *    The data of the treegraph series needs to be formatted in such a way, that
 *    there are no circular dependencies on the nodes
 *
 *  ```js
 *     data: [{
 *         id: 'Category1'
 *     }, {
 *         id: 'Category1',
 *         parent: 'Category2',
 *     }]
 *  ```
 *
 * @type      {Array<*>}
 * @extends   series.treemap.data
 * @product   highcharts
 * @excluding outgoing, weight, value
 * @apioption series.treegraph.data
 */
