+# AG Grid Enterprise + AG Charts Enterprise v2.0.0 Release Notes
+
+## Overview
+Version 2.0.0 introduces **Grid-to-Charts Data Binding** — a comprehensive framework for synchronizing AG Grid data with AG Charts Enterprise, enabling coordinated dashboards with cross-filtering and selection sync.
+
+## New Features
+
+### Grid ↔ Charts Data Binding
+- **Unified Data Model**: Single data source powers both grid and charts with automatic synchronization.
+- **Cross-Filtering**: Chart interactions filter grid rows; grid filters update charts in real-time.
+- **Selection Sync**: Grid row selection highlights corresponding chart data points and vice versa.
+- **Custom Data Bridges**: Implement `IChartDataBridge<T>` for domain-specific data transformations and coordination logic.
+- **Registry Pattern**: Centralized `ChartRegistry` manages chart instances, relationships, and event lifecycle.
+
+### Core Components (New)
+
+#### `IChartDataBridge<T>`
+Abstraction layer for bidirectional data synchronization:
+- Generic over row data type (POJO, Map, custom types)
+- Methods: `getGridRowData()`, `onGridDataChanged()`, `onGridSelectionChanged()`, `onChartInteraction()`
+- Field mapping support for grid column → chart property projection
+- Listener pattern for chart interaction events
+
+#### `ChartConfiguration`
+Metadata container for chart-grid relationships:
+- 58 fluent properties for complete chart customization
+- Chart ID, type, title, themes
+- Data bridge and grid references
+- Field mapping configuration
+- Feature flags: enableCrossFiltering, enableSelectionSync
+- Theme overrides and custom options
+
+#### `ChartRegistry`
+Singleton registry for lifecycle and relationship management:
+- Thread-safe with ConcurrentHashMap
+- Manages chart registration, data bridges, and grid-chart linking
+- Event listener support for chart lifecycle
+- Retrieve linked charts by grid ID
+
+### AgGridEnterprise Helper Methods
+Five new fluent methods for simplified chart integration:
+
+1. **`linkCharts(String... chartIds)`** — Link pre-registered charts by ID
+2. **`registerAndLinkChart(ChartConfiguration config)`** — Create and link atomically
+3. **`enableChartCrossFiltering()`** — Activate bidirectional filtering
+4. **`enableChartSelectionSync()`** — Enable selection highlighting
+5. **`getChartRegistry()`** — Static accessor to ChartRegistry singleton
+
+All methods follow CRTP pattern: return `(J) this` for method chaining.
+
+## Integration Patterns
+
+### Basic Linking
+```java
+grid.registerAndLinkChart(new ChartConfiguration("chart1", "bar")
+    .setTitle("Sales by Region")
+    .setFieldMapping(Map.of("region", "x", "sales", "y")));
+```
+
+### Cross-Filtering
+```java
+grid.registerAndLinkChart(new ChartConfiguration("chart1", "line")
+    .setTitle("Sales Trend")
+    .setEnableCrossFiltering(true)
+    .setFieldMapping(Map.of("month", "x", "amount", "y")))
+    .enableChartCrossFiltering();
+```
+
+### Selection Sync
+```java
+grid.enableCharts()
+    .registerAndLinkChart(new ChartConfiguration("chart1", "pie")
+        .setTitle("Market Share")
+        .setEnableCrossFiltering(true)
+        .setEnableSelectionSync(true)
+        .setFieldMapping(Map.of("competitor", "label", "share", "value")))
+    .enableChartSelectionSync();
+```
+
+### Custom Data Bridge
+```java
+class SalesDataBridge implements IChartDataBridge<SalesRecord> {
+    @Override
+    public List<SalesRecord> getGridRowData() {
+        return salesService.getRecords();
+    }
+
+    @Override
+    public void onGridDataChanged(List<SalesRecord> newData) {
+        ChartRegistry.getInstance().updateChartData("salesChart", newData);
+    }
+
+    @Override
+    public Map<String, String> getFieldMapping() {
+        return Map.of("region", "x", "sales", "y");
+    }
+}
+
+ChartRegistry.getInstance()
+    .registerDataBridge("bridge1", new SalesDataBridge())
+    .registerChart(new ChartConfiguration("salesChart", "bar")
+        .setTitle("Sales Analysis")
+        .setDataBridgeId("bridge1"));
+```
+
+## Architecture
+
+### Data Flow
+```
+┌─────────────────┐
+│  Grid Data      │
+│  (Row Model)    │
+└────────┬────────┘
+         │
+         ├─────────────────────────┐
+         │                         │
+         v                         v
+    [ChartRegistry]          [ChartRegistry]
+         │                         │
+    Chart #1          ◄────────► Chart #2
+    (Bar Chart)        Cross-    (Line Chart)
+                       Filtering
+         │                         │
+         └────────────┬────────────┘
+                      │
+              [Grid Selection Sync]
+                      │
+                  Row Highlight
+```
+
+### Thread Safety
+- `ChartRegistry` uses `ConcurrentHashMap` for thread-safe access
+- Safe for multi-threaded grid updates and chart interactions
+- Event listeners are notified asynchronously
+
+### Registry Event Lifecycle
+1. `onChartRegistered(ChartConfiguration)` — Chart added to registry
+2. `onChartUnregistered(String chartId)` — Chart removed from registry
+3. `onChartsLinkedToGrid(String gridId, List<String> chartIds)` — Charts associated with grid
+4. `onDataBridgeRegistered(String bridgeId, IChartDataBridge)` — Data bridge added
+5. `onChartDataUpdated(String chartId, List<Map>)` — Chart data refreshed
+
+## Field Mapping Reference
+
+### Bar / Column Charts
+- Grid columns map to: `x` (category), `y` (series values), `color` (optional)
+- Example: `region→x, sales→y, quarter→color`
+
+### Line Charts
+- Grid columns map to: `x` (x-axis), `y` (series), `strokeColor` (optional)
+- Example: `date→x, revenue→y, department→strokeColor`
+
+### Pie / Doughnut Charts
+- Grid columns map to: `label` (segment labels), `value` (segment sizes)
+- Example: `category→label, percentage→value`
+
+### Scatter Charts
+- Grid columns map to: `x` (x-axis), `y` (y-axis), `size` (optional), `color` (optional)
+- Example: `height→x, weight→y, age→size`
+
+### Waterfall Charts
+- Grid columns map to: `x` (categories), `y` (values), `isIntermediateTotal`, `isTotal`
+- Example: `month→x, amount→y, isQuarterEnd→isIntermediateTotal`
+
+## Best Practices
+
+### IDs and References
+- Use consistent, descriptive chart IDs: `"sales-regional"`, `"forecast-monthly"`
+- Grid IDs auto-generated; access via `getGridId()` (private, but used internally)
+- Bridge IDs should indicate data source: `"bridge-sales"`, `"bridge-forecast"`
+
+### Field Mapping
+- Define mappings before linking charts
+- Validate grid column names against data model
+- Use consistent naming: snake_case or camelCase throughout
+- Document custom field transformations in `IChartDataBridge`
+
+### Data Bridges
+- Implement for custom transformations (filtering, aggregation, calculation)
+- Keep synchronous; use async tasks only for heavy computations outside grid
+- Store computed data in bridge instance variables if needed
+- Test field mapping with sample data before deployment
+
+### Performance
+- Large datasets (>10K rows): aggregate on server before charting
+- Enable cross-filtering selectively; it has CPU cost on interactions
+- Use pagination for grids with charts to reduce rendering overhead
+- Profile chart update performance; consider debouncing rapid grid changes
+
+### Error Handling
+- Catch `NullPointerException` when accessing unregistered bridge IDs
+- Validate field mapping exists before `enableChartCrossFiltering()`
+- Log chart interaction errors; don't fail grid updates on chart exceptions
+- Fail fast on registration; use try-catch around `registerAndLinkChart()`
+
+## Migration from v1.x
+
+- **No breaking changes**: Existing grid and chart code continues to work unchanged
+- **Additive only**: New chart binding APIs are optional; use when needed
+- **Backward compatible**: Community plugin still works; enterprise features enhance it
+- **Opt-in**: Chart linking requires explicit `registerAndLinkChart()` or `linkCharts()` calls
+

 # AgCharts Enterprise Integration — Rules
 
-Overview
+## Overview
 - This module extends the community AgCharts plugin to activate AG Charts Enterprise features in JWebMP applications.
 - It mirrors the model used by WebAwesomePro extending WebAwesome and FullCalendarPro extending FullCalendar.
+- **New in v2.0.0**: Integrated grid-to-charts data binding for synchronized dashboards with cross-filtering and selection sync.
 
-Usage patterns
+## Usage patterns
+
+### Basic Usage
 - Add Maven dependency: com.jwebmp.plugins:agcharts-enterprise:${version} (version via BOM recommended).
 - Keep community plugin dependency present: com.jwebmp.plugins:agcharts.
 - Use charts as normal through JWebMP; enterprise features become available on the client when the Page Configurator includes the TypeScript dependency for `ag-charts-enterprise`.
 - Reference architecture & sequence diagrams in `docs/architecture/` via `docs/PROMPT_REFERENCE.md` before generating code; they define the required containers and build flow.
 
-Minimal example
+### Grid-Charts Integration (v2.0.0+)
+- Link AG Grid data to AG Charts Enterprise for coordinated dashboards.
+- Enable cross-filtering: chart selections filter grid rows; grid filters update charts.
+- Enable selection sync: grid row selection highlights chart data points.
+- Use `IChartDataBridge` for custom data transformations and event coordination.
+- Manage charts via centralized `ChartRegistry` for lifecycle and relationship tracking.
+- See `grid-data-binding.rules.md` for detailed patterns and API reference.
+
+## Minimal example
+
+### Charts Only
 - Server-side (Java/JWebMP): continue to construct charts as with the community plugin; no API change required for basic usage.
 - Ensure the Page Configurator from this module is on the classpath (auto-discovery via Java ServiceLoader and JWebMP conventions).
 
-Quick start checklist
+### Grid + Charts (v2.0.0+)
+```java
+// Create grid with data
+AgGridEnterprise<AgGridEnterprise<?>> grid = new AgGridEnterprise<>("salesGrid")
+    .setRowData(loadSalesData())
+    .enableCharts()
+
+    // Register and link a chart
+    .registerAndLinkChart(new ChartConfiguration("regionChart", "pie")
+        .setTitle("Sales by Region")
+        .setFieldMapping(Map.of(
+            "region", "label",
+            "sales", "value",
+            "regionId", "id"
+        ))
+        .setEnableCrossFiltering(true))
+
+    // Enable coordination features
+    .enableChartCrossFiltering();
+```
+
+## Quick start checklist
+
 1. Import the JWebMP BOM plus `com.jwebmp.plugins:agcharts` and this module.
 2. Confirm ServiceLoader discovery: `META-INF/services/com.jwebmp.core.services.IPageConfigurator` includes `AgChartsEnterprisePageConfigurator`.
-3. Annotate charts via CRTP fluent APIs (see ./java-usage-guide.rules.md and ./usage-examples.rules.md for patterns).
-4. Run a build (`mvn clean package`); verify generated Angular `package.json` lists `ag-charts-enterprise` and `ag-charts-angular`.
-5. Provide AG Charts Enterprise license initialization per ./licensing-and-activation.rules.md if required by your deployment.
+3. **For Grid+Charts**: Use `AgGridEnterprise.registerAndLinkChart()` or `ChartRegistry.getInstance().registerChart()` to establish chart-grid relationships.
+4. Annotate charts via CRTP fluent APIs (see ./java-usage-guide.rules.md and ./usage-examples.rules.md for patterns).
+5. Run a build (`mvn clean package`); verify generated Angular `package.json` lists `ag-charts-enterprise` and `ag-charts-angular`.
+6. Provide AG Charts Enterprise license initialization per ./licensing-and-activation.rules.md if required by your deployment.
 
-Configuration
-- TypeScript dependency: `ag-charts-enterprise` is pulled in by the Page Configurator using @TsDependency.
+## Configuration
+
+### TypeScript dependency
+- `ag-charts-enterprise` is pulled in by the Page Configurator using @TsDependency.
 - Angular peer dependencies: community plugin typically includes `ag-charts-community` and `ag-charts-angular`; this enterprise plugin complements them.
 
-Performance/constraints
+### Grid-Charts Coordination (v2.0.0+)
+- Register charts via `ChartRegistry` or `grid.registerAndLinkChart()`.
+- Define field mappings to sync grid columns with chart properties.
+- Enable cross-filtering and selection sync on `ChartConfiguration` or via grid helper methods.
+- Optionally implement custom `IChartDataBridge` for complex data flows.
+
+## Performance/constraints
+
 - Do not bundle or edit generated TS; rely on the build to include dependencies.
 - Enterprise features may increase bundle size; tree-shake when possible.
 - Licensing is required per AG Charts Enterprise terms; see licensing-and-activation.rules.md.
+- **For large datasets**: Implement server-side aggregation before charting to avoid performance degradation.
