Original Pull Request: https://github.com/langchain-ai/langgraph/pull/4886

State: closed
Merged: Yes

The current Build a basic chatbot tutorial shows a graph diagram that includes both a START and an END node. However, the tutorial does not define or mention the END node at all, which may cause confusion.

Running the code as-is from the current version of this tutorial does not produce a graph matching the image shown in the tutorial.

This PR adds documentation and code for adding the END node as well. The alternative was to update the image, but it might be more valuable to show users how to add an exit point explicitly.
