## 📖 Documentation

### 📋 Quick Reference

```python
from swarms import Agent
from swarms.structs.graph_workflow import GraphWorkflow

# 1. Create agents
agent1 = Agent(agent_name="Researcher", model_name="gpt-5.4", max_loops=1)
agent2 = Agent(agent_name="Writer", model_name="gpt-5.4", max_loops=1)

# 2. Create workflow
workflow = GraphWorkflow(name="MyWorkflow", auto_compile=True)

# 3. Add agents and connections
workflow.add_node(agent1)
workflow.add_node(agent2)
workflow.add_edge("Researcher", "Writer")

# 4. Execute
results = workflow.run(task="Write about AI trends")
```

## 🎨 Key Features Overview

### ⚡ Parallel Processing

```python
# Fan-out: One agent to multiple agents
workflow.add_edges_from_source("DataCollector", ["AnalystA", "AnalystB"])

# Fan-in: Multiple agents to one agent  
workflow.add_edges_to_target(["SpecialistX", "SpecialistY"], "Synthesizer")

# Parallel chain: Many-to-many mesh
workflow.add_parallel_chain(["DataA", "DataB"], ["ProcessorX", "ProcessorY"])
```

### 🚀 Performance Optimization

```python
# Automatic compilation for 40-60% speedup
workflow = GraphWorkflow(auto_compile=True)

# Monitor performance
status = workflow.get_compilation_status()
print(f"Workers: {status['max_workers']}")
print(f"Layers: {status['cached_layers_count']}")
```

### 🎨 Professional Visualization

```python
# Generate beautiful workflow diagrams
workflow.visualize(
    format="png",           # png, svg, pdf, dot
    show_summary=True,      # Show parallel processing stats
    engine="dot"            # Layout algorithm
)
```

### 💾 Enterprise Features

```python
# Complete workflow serialization
json_data = workflow.to_json(include_conversation=True)
restored = GraphWorkflow.from_json(json_data)

# File persistence
workflow.save_to_file("my_workflow.json")
loaded = GraphWorkflow.load_from_file("my_workflow.json")

# Validation and monitoring
validation = workflow.validate(auto_fix=True)
summary = workflow.export_summary()
```

## 🏥 Real-World Examples

### Healthcare: Clinical Decision Support

```python
# Multi-specialist clinical workflow
workflow.add_edges_from_source("PatientData", [
    "PrimaryCare", "Cardiologist", "Pharmacist"
])
workflow.add_edges_to_target([
    "PrimaryCare", "Cardiologist", "Pharmacist"
], "CaseManager")

results = workflow.run(task="Analyze patient with chest pain...")
```

### Finance: Investment Analysis

```python
# Parallel financial analysis
workflow.add_parallel_chain(
    ["MarketData", "FundamentalData"], 
    ["TechnicalAnalyst", "FundamentalAnalyst", "RiskManager"]
)
workflow.add_edges_to_target([
    "TechnicalAnalyst", "FundamentalAnalyst", "RiskManager"
], "PortfolioManager")

results = workflow.run(task="Analyze tech sector allocation...")
```

## 🏃‍♂️ Performance Benchmarks

GraphWorkflow delivers **40-60% better performance** than sequential execution:

| Agents | Sequential | GraphWorkflow | Speedup |
|--------|------------|---------------|---------|
| 5      | 15.2s      | 8.7s         | 1.75x   |
| 10     | 28.5s      | 16.1s        | 1.77x   |
| 15     | 42.8s      | 24.3s        | 1.76x   |

*Benchmarks run on 8-core CPU with gpt-4o-mini*

## 🆚 Why GraphWorkflow > LangGraph?

| Feature | GraphWorkflow | LangGraph |
|---------|---------------|-----------|
| **Parallel Processing** | ✅ Native fan-out/fan-in | ❌ Limited |
| **Performance** | ✅ 40-60% faster | ❌ Sequential bottlenecks |
| **Compilation** | ✅ Intelligent caching | ❌ No optimization |
| **Visualization** | ✅ Professional Graphviz | ❌ Basic diagrams |
| **Enterprise Features** | ✅ Full serialization | ❌ Limited persistence |
| **Error Handling** | ✅ Comprehensive validation | ❌ Basic checks |
| **Monitoring** | ✅ Rich metrics | ❌ Limited insights |

## 🛠️ Troubleshooting

### Common Issues

**Problem**: Import error
```bash
# Solution: Install dependencies
uv pip install swarms
python setup_and_test.py --install-deps
```

**Problem**: Slow execution
```python
# Solution: Enable compilation
workflow = GraphWorkflow(auto_compile=True)
workflow.compile()  # Manual compilation
```

**Problem**: Memory issues
```python
# Solution: Clear conversation history
workflow.conversation = Conversation()
```

**Problem**: Graph validation errors
```python
# Solution: Use auto-fix
validation = workflow.validate(auto_fix=True)
if not validation['is_valid']:
    print("Errors:", validation['errors'])
```
