Quick-start (2 mins) 1. Drop the ReactFlowElement on the page → it renders an empty canvas.
2. Create nodes with add_node (or preload from DB) – give each a handler (e.g. “multiply”).
3. Connect them by dragging from bottom handle to top handle.
4. In a workflow, add onNodeExecute → switch on handler → do stuff → set_node_output.
5. Trigger run_flow → watch nodes light up live.
6. Need background processing? Save nodes & edges JSON, call run_flow_server in a backend workflow.

That’s it—draw your flow, wire Bubble workflows to each node, run anywhere.
