+│  [+HTTP] [+Script] [+Cond]   │  Node Configuration  │
+│                              │                      │
+│  ┌───────┐ ┌───────┐        │  Label: [_____]      │
+│  │Node 1 │ │Node 2 │        │  Type:  [HTTP▼]      │
+│  │ HTTP  │ │Script │        │                      │
+│  └───────┘ └───────┘        │  URL:   [_____]      │
+│                              │  Method:[GET ▼]      │
+│  ┌───────┐ ┌───────┐        │                      │
+│  │Node 3 │ │Node 4 │        │  [Save] [Delete]     │
+│  │ Delay │ │ Loop  │        │                      │
+│  └───────┘ └───────┘        │                      │
+└──────────────────────────────┴──────────────────────┘
+```
+

+);
+```
+
+## Future Enhancements (Optional)
+
+While the current implementation is complete, the following enhancements could be considered in future iterations:
+
+1. **Visual Workflow Connections**
+   - Draw lines between nodes to show flow

+
+2. **Drag & Drop Positioning**
+   - Allow manual node repositioning on canvas
+   - Save x/y coordinates in node data
+
+3. **Workflow Execution Engine**
+   - Backend execution engine to run workflows
+   - Queue management for concurrent executions
+
+4. **Real-time Monitoring**
+   - Live execution status updates
+   - Detailed execution logs per node
+
+5. **Workflow Templates**
+   - Pre-built workflow templates for common tasks
+   - Template marketplace/library
+
+6. **Import/Export**
+   - Export workflows as JSON
+   - Import workflows from files
+
+7. **Advanced Validation**
+   - Detect circular dependencies
+   - Validate node connections
+   - Required field validation
+
+8. **Version Control**

+   - Rollback to previous versions
+   - Compare versions
+
+## Conclusion
