Been doing a ton more with Langgraph lately…maybe I have seen the light. Figured I’d whip something up for my weekly video to share with y’all.

This pretty much covers all the fundamentals you need to get up and running with langgraph. Importing a LLM, setting up the state, constructing the graph itself and then calling it. Also noticed a little bug with the yfinance documentation but I covered it in the video, just make sure you use size=5 instead of count=5 and you should be good to go.

Anyway, love ya all. Happy coding!
