/**
 * DataViz Generator — Creates chart/graph components from DataVizSpec objects.
 *
 * Inputs:
 *   - DataVizSpec (from src/specs/types.ts) — defines chartType, dataShape, interactions, etc.
 *   - CodegenContext — provides design system tokens and project context.
 *
 * Outputs:
 *   - DataVizCode: { chart: string (TSX), barrel: string (index.ts) }
 *
 * Key responsibilities:
 *   1. Map chartType to the correct Recharts component import and JSX
 *   2. Generate typed data-point interface from dataShape fields
 *   3. Wrap chart in shadcn Card for consistent visual framing
 *   4. Emit an accessible <details> data-table fallback when spec.accessibility.dataTableFallback is true
 *   5. Inline sample data constant when spec.sampleData is provided
