    /**
     * [REQUIREMENT_MEMO]:
     * (0) `metaRawOption` means `dimensions`/`sourceHeader`/`seriesLayoutBy` in raw option.
     * (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 transforms.
     * 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: {...} }
