 * The data of the highlighted item.
 * To highlight an item, you need to provide the series id and the item id.
 * If targeting the whole series, you can omit the item id.
 * To clear the highlight, set the value to an empty object.
 *
 * @example
 * // Highlight the item with the series id 'london' and the item id 0.
 * { seriesId: 'london', dataIndex: 0 }
 *
 * // Highlight the whole series with the series id 'london'.
 * { seriesId: 'london' }
 *
 * // Clear the highlight.
