 * "others" vs "others": do not change order (always return 0).
 * "numeric" vs "non-numeric-string": "non-numeric-string" is treated as "incomparable".

 * [REQUIREMENT_MEMO]:

 * (1) Keep support the feature: `metaRawOption` can be specified both on `series` and
 * `root-dataset`. Them on `series` has higher priority.
 * (2) Do not support to set `metaRawOption` on a `non-root-dataset`, because it might
 * confuse users: whether those props indicate how to visit the upstream source or visit
 * the transform result source, and some transforms has nothing to do with these props,
 * and some transforms might have multiple upstream.
 * (3) Transforms should specify `metaRawOption` in each output, just like they can be
 * declared in `root-dataset`.
 * (4) At present only support visit source in `SERIES_LAYOUT_BY_COLUMN` in transforms.
 * That is for reducing complexity in transfroms.
 * PENDING: Whether to provide transposition transform?
 *
 * [IMPLEMENTAION_MEMO]:
 * "sourceVisitConfig" are calculated from `metaRawOption` and `data`.
 * They will not be calculated until `source` is about to be visited (to prevent from
 * duplicate calcuation). `source` is visited only in series and input to transforms.
 *
 * [DIMENSION_INHERIT_RULE]:
 * By default the dimensions are inherited from ancestors, unless a transform return
 * a new dimensions definition.
 * Consider the case:
 * ```js
 * dataset: [{
 *     source: [ ['Product', 'Sales', 'Prise'], ['Cookies', 321, 44.21], ...]
 * }, {
 *     transform: { type: 'filter', ... }
 * }]
 * dataset: [{
 *     dimension: ['Product', 'Sales', 'Prise'],
 *     source: [ ['Cookies', 321, 44.21], ...]
 * }, {
 *     transform: { type: 'filter', ... }
 * }]
 * ```
 * The two types of option should have the same behavior after transform.
 *
 *
 * [SCENARIO]:
 * (1) Provide source data directly:
 * ```js
 * series: {
 *     encode: {...},
 *     dimensions: [...]
 *     seriesLayoutBy: 'row',
 *     data: [[...]]
 * }
 * ```
 * (2) Series refer to dataset.
 * ```js
 * series: [{
 *     encode: {...}
 *     // Ignore datasetIndex means `datasetIndex: 0`
 *     // and the dimensions defination in dataset is used
 * }, {
 *     encode: {...},
 *     seriesLayoutBy: 'column',
 *     datasetIndex: 1
 * }]
 * ```
 * (3) dataset transform
 * ```js
 * dataset: [{
 *     source: [...]
 * }, {
 *     source: [...]
 * }, {
 *     // By default from 0.
 *     transform: { type: 'filter', config: {...} }
 * }, {
 *     // Piped.
 *     transform: [
 *         { type: 'filter', config: {...} },
 *         { type: 'sort', config: {...} }
 *     ]
 * }, {
 *     id: 'regressionData',
 *     fromDatasetIndex: 1,
 *     // Third-party transform
 *     transform: { type: 'ecStat:regression', config: {...} }
 * }, {
 *     // retrieve the extra result.

/**
 * ----------------------------------------------------------
 * [STRATEGY_MERGE] Merge properties or erase all properties:
 *
 * Based on the fact that the existing zr element probably be reused, we now consider whether
 * merge or erase all properties to the exsiting elements.
 * That is, if a certain props is not specified in the lastest return of `renderItem`:
 * + "Merge" means that do not modify the value on the existing element.
 * + "Erase all" means that use a default value to the existing element.
 *
 * "Merge" might bring some unexpected state retaining for users and "erase all" seams to be
 * more safe. "erase all" force users to specify all of the props each time, which is recommanded
 * in most cases.
 * But "erase all" theoretically disables the chance of performance optimization (e.g., just
 * generete shape and style at the first time rather than always do that).
 * So we still use "merge" rather than "erase all". If users need "erase all", they can
 * simple always set all of the props each time.
 * Some "object-like" config like `textConfig`, `textContent`, `style` which are not needed for
 * every elment, so we replace them only when user specify them. And the that is a total replace.
 *
 * TODO: there is no hint of 'isFirst' to users. So the performance enhancement can not be
 * performed yet. Consider the case:
 * (1) setOption to "mergeChildren" with a smaller children count
 * (2) Use dataZoom to make an item disappear.
 * (3) User dataZoom to make the item display again. At that time, renderItem need to return the
 * full option rather than partial option to recreate the element.
 *
 * ----------------------------------------------
 * [STRATEGY_NULL] `hasOwnProperty` or `== null`:
 *
 * Ditinguishing "own property" probably bring little trouble to user when make el options.
 * So we  trade a {xx: null} or {xx: undefined} as "not specified" if possible rather than
 * "set them to null/undefined". In most cases, props can not be cleared. Some typicall
 * clearable props like `style`/`textConfig`/`textContent` we enable `false` to means
 * "clear". In some othere special cases that the prop is able to set as null/undefined,
 * but not suitable to use `false`, `hasOwnProperty` is checked.
 *
 * ---------------------------------------------
 * [STRATEGY_TRANSITION] The rule of transition:
 * + For props on the root level of a element:
 *      If there is no `transition` specified, tansform props will be transitioned by default,
 *      which is the same as the previous setting in echarts4 and suitable for the scenario
 *      of dataZoom change.
 *      If `transition` specified, only the specified props will be transitioned.
 * + For props in `shape` and `style`:
 *      Only props specified in `transition` will be transitioned.
 * + Break:
 *      Since ec5, do not make transition to shape by default, because it might result in
 *      performance issue (especially `points` of polygon) and do not necessary in most cases.
 *
 * @return if `isMorphTo`, return `allPropsFinal`.
