StateWeave graph state can be visualized as nodes and edges. 
import { graphToMermaid } from "stateweave";

const mermaid = graphToMermaid(result.graph);
console.log(mermaid);
Example output: In the CLI: 
pnpm cli "Find why login fails after token refresh." --graph
Or toggle it interactively: 
/graph
This keeps visualization dependency-free. A future UI can render the same StateGraph with any graph library.
