LangChain - LangGraph for Stateful Agents

Why does LangGraph use nodes and edges to represent agent flows?

ATo store data in a flat list format.

BTo limit the flow to only two steps.

CTo avoid using any conditions in the flow.

DTo model decision points and transitions clearly.

Step-by-Step Solution

Solution:

Step 1: Understand graph structure basics
Graphs use nodes to represent states or actions and edges to represent transitions or decisions.
Step 2: Apply this to agent flows
Using nodes and edges models decision points and transitions clearly, which is essential for complex flows.
Final Answer:
To model decision points and transitions clearly. -> Option D
Quick Check:
Graph structure = Clear decision modeling [OK]

Quick Trick: Nodes = states, edges = transitions [OK]
