Let’s break this down in simple terms. LangGraph is built around graphs—and yeah, that’s obviously where the name comes from. Graphs have three main parts here: nodes, edges, and state. Imagine you’re planning a road trip. The nodes are the steps where something happens—like grabbing coffee or refueling the car. The edges are the roads that connect those stops, deciding which way to go next. And the state? That’s like your travel journal, keeping track of where you’ve been, where you are now, and what you’ve picked up along the way.
