- Interface-based data modeling
- Type-safe component APIs
- Generic type support for custom data

```typescript
import { Graphin } from '@antv/graphin';
import type { IUserNode, IUserEdge } from '@antv/graphin';

interface CustomNodeData extends IUserNode {
  type: 'service' | 'database';
  metrics: {
    cpu: number;
    memory: number;
  };
}

const MyGraph: React.FC = () => {
  const [data, setData] = useState<{
    nodes: CustomNodeData[];
    edges: IUserEdge[];
  }>({ nodes: [], edges: [] });

  return <Graphin data={data} />;
};
```

**Source:** [Graphin packages/graphin](https://github.com/antvis/graphin/tree/master/packages/graphin)

### Hook-based API

**useGraphin Hook:**

```typescript
import { useGraphin } from '@antv/graphin';

const MyComponent = () => {
  const { graph, isReady } = useGraphin();

  useEffect(() => {
    if (isReady) {
      // Access G6 graph instance
      graph.on('node:click', (evt) => {
        console.log('Node clicked:', evt.item);
      });
    }
  }, [isReady]);

  return <div>Graph is {isReady ? 'ready' : 'loading'}</div>;
};
```

### State Management Patterns

**Built-in State Management:**

- G6 provides interaction states (hover-activate, click-select)
- Access via `data.states` field
- Conditional styling based on state

**Integration with React State:**

```typescript
import { useState, useEffect, useMemo } from 'react';
import { Graphin } from '@antv/graphin';

const GraphComponent = () => {
  const [rawData, setRawData] = useState(null);
  const [selectedNode, setSelectedNode] = useState(null);

  // Memoize graph options
  const options = useMemo(() => ({
    layout: { type: 'force' },
    modes: { default: ['drag-canvas', 'zoom-canvas'] }
  }), []);

  // React manages state, Graphin handles rendering
  useEffect(() => {
    fetchGraphData().then(setRawData);
  }, []);

  return (
    <Graphin
      data={rawData}
      options={options}
      onNodeClick={(evt) => setSelectedNode(evt.item)}
    />
  );
};
```

## Advanced Capabilities

### 1. Virtual Rendering Techniques

**Viewport-Based Rendering:**

- Automatic culling of off-screen elements
- G6 5.0+ automatically crops graphics outside viewport
- 2-3x improvement in picking performance (hover/click)
- No configuration required - automatic optimization

**Source:** [G6 4.0: More Progress for Easier Graph Visual Analysis](https://medium.com/antv/g6-4-0-more-progress-for-easier-graph-visual-analysis-9e8e98f099e9)

### 2. Level of Detail (LOD)

**Implementation Strategy:**

- Not built-in, but achievable via custom rendering
- Use multi-scale representation preprocessing
- Render appropriate detail level based on zoom
- Decouples rendering cost from scene complexity

**Recommended Approach:**

```typescript
graph.on('viewportchange', (evt) => {
  const zoom = graph.getZoom();
  if (zoom < 0.5) {
    // Low detail: simple shapes, no labels
    graph.updateItem(node, { style: { lineWidth: 1 } });
  } else if (zoom < 1.0) {
    // Medium detail: basic labels
    graph.updateItem(node, { labelCfg: { visible: true } });
  } else {
    // High detail: full rendering
    graph.updateItem(node, {
      /* full config */
    });
  }
});
```

### 3. Edge Bundling

**Built-in Edge Bundling Plugin:**

- Based on FEDB (Force-Directed Edge Bundling) algorithm
- Models edges as flexible springs
- Self-organizing bundling process
- Configuration:

```typescript
import { EdgeBundling } from '@antv/g6';

const graph = new Graph({
  plugins: [
    new EdgeBundling({
      bundleThreshold: 0.6, // Compatibility threshold (0-1)
      // Higher = fewer bundled edges
      // Lower = more aggressive bundling
    }),
  ],
});
```

**Source:** [Edge Bundling | G6](http://g6-v3-2.antv.vision/en/docs/manual/cases/edgeBundling/)

### 4. Node and Edge Aggregation

**Large Graph Solutions:**

- Node aggregation: Group similar nodes
- Edge aggregation: Combine multiple edges
- Node clustering: Hierarchical grouping
- Prevents "hairball" visualizations

**Implementation:**

```typescript
// Example: Aggregate nodes by type
const aggregatedData = {
  nodes: data.nodes.reduce((acc, node) => {
    const type = node.type;
    if (!acc[type]) {
      acc[type] = {
        id: `${type}-group`,
        type: 'aggregate',
        count: 0,
        children: [],
      };
    }
    acc[type].count++;
    acc[type].children.push(node);
    return acc;
  }, {}),
};
```

### Bundle Size Analysis

**Package Sizes (Approximate):**

```
@antv/g6              ~500KB (minified)
@antv/graphin         ~100KB (minified)
@antv/graphin-components  ~80KB (minified)
@antv/algorithm       ~150KB (minified)

Total (all packages): ~830KB minified
Gzipped estimate:     ~250-300KB
```

**Tree-Shaking Effectiveness:**

- ✅ ES modules support
- ✅ Side effects declared (CSS only)
- ✅ Import specific components
- ⚠️ G6 core is large even with tree-shaking
- ⚠️ Layout algorithms add significant size

**Optimization Strategies:**

1. Import specific components only
2. Use dynamic imports for large features
3. Split vendor bundles appropriately
4. Consider CDN for common libraries

```typescript
// Good: Tree-shakable
import { Graphin } from '@antv/graphin';
import { Toolbar } from '@antv/graphin-components';

// Bad: Imports everything
import * as Graphin from '@antv/graphin';
```

### Security Considerations

**License:** MIT (permissive, enterprise-friendly)

**Dependencies:**

- Moderate dependency tree
- Alibaba-maintained packages
- Regular security updates
- No known critical vulnerabilities

**Best Practices:**

1. Keep packages updated
2. Review dependency tree regularly
3. Use npm audit / bun audit
4. Monitor Alibaba security advisories

// TraceGraphView.tsx
import React, { useState, useEffect, useMemo } from 'react';
import { Graphin, Utils } from '@antv/graphin';
import { Toolbar, MiniMap, ContextMenu } from '@antv/graphin-components';

interface TraceNode {
  id: string;
  type: 'requirement' | 'test' | 'code';
  label: string;
  metadata: Record<string, any>;
}

interface TraceEdge {
  source: string;
  target: string;
  type: 'implements' | 'tests' | 'traces';
}

const TraceGraphView: React.FC = () => {
  const [data, setData] = useState<{
    nodes: TraceNode[];
    edges: TraceEdge[];
  }>({ nodes: [], edges: [] });

  const [renderer, setRenderer] = useState<'canvas' | 'webgl'>('canvas');

  // Automatically switch to WebGL for large graphs
  useEffect(() => {
    const primitiveCount = data.nodes.length * 3 + data.edges.length * 2;
    if (primitiveCount > 30000 && renderer !== 'webgl') {
      setRenderer('webgl');
      console.log('Switched to WebGL renderer for performance');
    }
  }, [data, renderer]);

  const layout = useMemo(() => ({
    type: 'force',
    enableWorker: true, // Offload to Web Worker
    preventOverlap: true,
    nodeSize: 30,
    linkDistance: 100,
    // GPU acceleration when available
    gpgpu: {
      enabled: true,
      onError: (err: Error) => {
        console.warn('GPU layout failed, falling back to CPU:', err);
      }
    }
  }), []);

  const modes = useMemo(() => ({
    default: [
      'drag-canvas',
      'zoom-canvas',
      'drag-node',
      'click-select',
      'activate-relations'
    ]
  }), []);

  return (
    <div style={{ height: '100vh', width: '100%' }}>
      <Graphin
        data={data}
        layout={layout}
        modes={modes}
        renderer={renderer}
        fitView
      >
        <Toolbar />
        <MiniMap />
        <ContextMenu />
      </Graphin>
    </div>
  );
};

export default TraceGraphView;
```
