# Graph with Reflection and Rewrite Nodes

This project provides a minimal directed graph implementation that supports two special node types:

- **ReflectionNode** – passes its input unchanged to its output.
- **RewriteNode** – transforms its input using a user‑supplied function.

## Installation

```bash
npm install
```

## Usage

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

const graph = new Graph();

// Create nodes
const start = new ReflectionNode('start');
const rewrite = new RewriteNode('rewrite', (x) => x * 2);

// Add nodes to graph
graph.addNode(start);
graph.addNode(rewrite);

// Connect nodes
graph.addEdge('start', 'rewrite');

// Evaluate graph
const result = graph.evaluate();
console.log(result); // { start: undefined, rewrite: 0 } (example)
```

## Running Tests

A simple test script (`test.js`) can be added to validate functionality. Run:

```bash
npm test
```
