/**
 * Transforms raw chart data into a structured, renderable format for series visualization.
 *
 * The DataModel is responsible for processing data through a multi-stage pipeline:
 * - Extracting and validating data from input datasets
 * - Grouping data by keys (for categorical axes or stacked series)
 * - Computing aggregations (sum, average, etc.) for grouped data
 * - Calculating domains (value ranges) for axes and scales
 * - Managing scoped data processing for multi-series charts
 * - Supporting incremental updates when data changes
 *
 * The class orchestrates several specialized subsystems:
 * - DataExtractor: Extracts and validates raw data
 * - DataGrouper: Groups data by keys
 * - Aggregator: Computes aggregations over grouped data
 * - DomainManager: Calculates and maintains value domains
 * - IncrementalProcessor: Handles efficient data updates
 *
 * Performance optimizations:
 *
 * 1. SHARED MEMORY OPTIMIZATION (groupsUnique=true):
 *    When each datum has unique keys, all groups share the same datumIndices array
 *    containing [0], since each datum's relative offset from its group is always 0.
 *
 * 2. BANDED DOMAIN PROCESSING:
 *    Large datasets are divided into bands for efficient domain calculation.
 *    Only dirty bands are recalculated during incremental updates.
 *
 * 3. BATCH MERGING:
 *    Column batches with identical characteristics (keys, invalidity) are merged
 *    to reduce processing overhead.
 *
 * 4. INCREMENTAL REPROCESSING:
 *    When supported, only changed data is reprocessed instead of full recalculation.
