# Graph with Reflection and Rewriting Nodes

This project implements a simple directed graph data structure in JavaScript that supports three types of nodes:

- **Generic Node** – the base node type.
- **Reflection Node** – represents a node that reflects on itself.
- **Rewriting Node** – represents a node that rewrites or transforms data.

## Installation

```bash
npm install
```

## Running Tests

```bash
npm test
```

## Usage

```js
import { Graph, Node, ReflectionNode, RewritingNode } from './src/index.js';

const graph = new Graph();

const n1 = new Node('n1');
const r1 = new ReflectionNode('r1');
const w1 = new RewritingNode('w1');

graph.addNode(n1);
graph.addNode(r1);
graph.addNode(w1);

graph.addEdge('n1', 'r1');
graph.addEdge('r1', 'w1');

graph.traverse('n1', (node) => {
  console.log(node.id, node.type);
});
```
