## How to Use

1. **Configuration** - Enter your datafake configuration in the editor
2. **Count** - Set the number of records to generate (1-100)
3. **Generate** - Press the Generate button or use **Ctrl+Enter** (Cmd+Enter on Mac)
4. **Load Examples** - Use the dropdown to load pre-built example configurations

## Configuration Structure

| Field | Description |
|-------|-------------|
| `metadata` | Optional name/version info |
| `variables` | Pre-generate values to reuse |
| `schema` | Define the output structure |

## The `fake` Operator

The `fake` operator is the core of datafake-rs. Use it to generate various types of fake data:

```json
{"fake": ["type"]}
{"fake": ["type", arg1, arg2]}
```

### Common Examples

| Type | Syntax | Description |
|------|--------|-------------|
| UUID | `{"fake": ["uuid"]}` | UUID v4 identifier |
| Name | `{"fake": ["name"]}` | Full name |
| Email | `{"fake": ["email"]}` | Email address |
| Integer | `{"fake": ["u8", 18, 65]}` | Integer with range |
| Float | `{"fake": ["f64", 0.0, 100.0]}` | Float with range |
| Choice | `{"fake": ["enum", "A", "B", "C"]}` | Random selection |
