# G6 v5 Graph Visualization

## Overview

G6 v5 is AntV's graph visualization engine for network diagrams, tree graphs, and relationship visualizations. It uses a **declarative configuration** style where `new Graph({...})` defines all nodes, edges, layouts, behaviors, and plugins in one constructor call.

```javascript
import { Graph } from '@antv/g6';

const graph = new Graph({
  container: 'container',
  data: {
    nodes: [{ id: 'node-1', style: { labelText: 'Node 1' } }],
    edges: [{ source: 'node-1', target: 'node-2' }],
  },
  layout: { type: 'force' },
  behaviors: ['drag-canvas', 'zoom-canvas', 'drag-element'],
});

await graph.render();
```

### CDN Usage

```html
<script src="https://unpkg.com/@antv/g6@5/dist/g6.min.js"></script>
<script>
  const graph = new G6.Graph({
    container: 'container',
    data: {
      nodes: [{ id: 'node-1', style: { labelText: 'Node 1' } }],
      edges: [{ source: 'node-1', target: 'node-2' }],
    },
    layout: { type: 'force' },
    behaviors: ['drag-canvas', 'zoom-canvas', 'drag-element'],
  });
  graph.render();
</script>
```

## Content Retrieval Service

When using AntV G6 for data visualization, if you need to understand the concepts, usage, API, examples, and other aspects of G6 v5, you can use the provided context retrieval service. When using the skill, content is retrieved via an antv HTTP API server using GET requests.

- Host: `https://sive.antv.antgroup.com`
- Endpoint: `/api/v1/context/retrieve`
- Method: `GET`
- Parameters: `query`, `library`, `topK`, `content`, `maxTokens`

Retrieve skills by query (hybrid search = FTS + vector + RRF fusion). Constraints docs are indexed as regular skill documents and will appear in search results naturally.

| Parameter | Type | Required | Description |
|---|---|---|---|
| `query` | string | ✅ | Search keywords, e.g. `force layout node` |
| `library` | string | ✅ | Library name: `g2`, `g6`, `x6` |
| `topK` | number | | Number of results to return (default: 5) |
| `content` | boolean | | Return full reference doc markdown (default: true) |
| `maxTokens` | number | | Max tokens per result (default: unlimited) |

```bash
curl "https://sive.antv.antgroup.com/api/v1/context/retrieve?query=force+layout+node+style&library=g6"
```

## Critical Rules

### MUST: Use `new Graph({...})` — NOT v4 `new G6.Graph()`

```javascript
// ❌ WRONG — v4 constructor
new G6.Graph({ container: 'container', ... });

// ✅ CORRECT — v5 constructor
import { Graph } from '@antv/g6';
new Graph({ container: 'container', ... });
```

### MUST: All config in one constructor call, `await graph.render()`

```javascript
// ❌ WRONG — v4 separate data method
graph.data(data);
graph.render();

// ✅ CORRECT — v5 declarative config + async render
const graph = new Graph({
  container: 'container',
  data: { nodes: [...], edges: [...] },
  layout: { type: 'force' },
  behaviors: ['drag-canvas', 'zoom-canvas'],
});
await graph.render();
```

### MUST: Data format with `id`, `source`, `target`

```javascript
// ❌ WRONG — missing node id, missing edge endpoints
const data = { nodes: [{ label: 'A' }], edges: [{ from: 'A', to: 'B' }] };

// ✅ CORRECT — each node has unique id, each edge has source/target
const data = {
  nodes: [{ id: 'node-1', style: { labelText: 'A' } }],
  edges: [{ source: 'node-1', target: 'node-2' }],
};
```

### MUST: Use `style.labelText` for labels — NOT `label` or `labelCfg`

```javascript
// ❌ WRONG — v4 label config
node: { labelCfg: { text: 'Node 1' } }

// ✅ CORRECT — v5 style.labelText
node: { style: { labelText: 'Node 1' } }
```

### MUST: `nodeStrength` must be ≥ 0 in force layout

```javascript
// ❌ WRONG — negative nodeStrength causes unpredictable behavior
layout: { type: 'force', nodeStrength: -300 }

// ✅ CORRECT — non-negative value
layout: { type: 'force', nodeStrength: 300 }
```

### MUST: `force` layout does NOT support `preventOverlap` / `nodeSize`

```javascript
// ❌ WRONG — v4 params silently ignored in v5
layout: { type: 'force', preventOverlap: true, nodeSize: 30 }

// ✅ CORRECT — use d3-force collide for overlap prevention
layout: { type: 'd3-force', collide: { radius: 30 } }
```

### MUST: No Mode concept — behaviors are flat array

```javascript
// ❌ WRONG — v4 mode-based behavior config
modes: { default: ['drag-canvas', 'zoom-canvas'] }

// ✅ CORRECT — v5 flat behavior array
behaviors: ['drag-canvas', 'zoom-canvas', 'drag-element']
```

### MUST: `container` is mandatory, default `'container'`

```javascript
// ❌ WRONG — no container specified
const graph = new Graph({ data });

// ✅ CORRECT
const graph = new Graph({ container: 'container', data, ... });
```
