Langchain1.0-Langgraph1.0-Learning and lc-studylab

These are complementary learning resources that serve different purposes: the first focuses on foundational agent development concepts and learning paths, while the second provides a comprehensive demonstration of LangChain's full ecosystem capabilities (LangGraph, RAG, Guardrails, etc.), so a developer would typically use both sequentially or in parallel to progress from fundamentals to advanced implementations.
