Graph Visualizer
Visualize and understand LangGraph state machine flows.
How Graphs Work
LangGraph uses a state machine architecture where:
- Nodes are functions that process and update state
- Edges define the flow between nodes
- Conditional edges enable dynamic routing based on state
Example Architectures
Simple Chatbot
ReAct Agent with Tools
Multi-Agent Supervisor
RAG Pipeline
Plan-and-Execute
