When to use this template

One event bus fanning out to billing, email, audit and the event store.. Use it when you need to show that producers do not know their consumers — the bus is the contract.

How to customize

  1. Add a step or node. Insert one line: node new_id 'New label' below anchor — placement is relative, so the solver re-flows the whole diagram instantly.
  2. Relabel an edge. Edit the text after the arrow: edge a -> b 'your label' — labels are the fastest way to carry rates, protocols or percentages.
  3. Change reading order. Swap a placement word: below to right of rotates a branch sideways without touching any other line.
