## 🎨 Quick Start Examples

### Basic Text Processing
```
"apple,banana,orange" → Text Splitter → ["apple", "banana", "orange"]
                                    ↓
["apple", "banana", "orange"] → Text Joiner → "apple | banana | orange"
```

### Text to JSON Conversion
```
'{"foo": "bar"}' → TextToJSON → { "foo": "bar" }
```

### Debug Workflow
```
Input Data → Debug Print ("Input") → Processing Node → Debug Print ("Output") → Result
```

### Timed Processing
```
Data → Wait (2.0s) → Processing → Wait (1.0s) → Output
```
