Today, we leave the world of linear "Chains" and enter the most powerful evolution of the LangChain ecosystem: LangGraph . If you've been following along, you've noticed that Chains always go forward: A -> B -> C . But real intelligence requires loops . Think about how you work: you write code, you run it, it fails, so you go back and fix it. That's a cycle. LangGraph is designed to let AI agents do exactly that. 🔄 Why LangGraph
