How to generate a state diagram

Tips on generating an State Diagram
  • Instead of writing a prompt from scratch, consider pasting excerpts from existing process requirements docs, log exports, or uploading image files.
  • Working with an LLM to create a fleshed out diagram prompt can be effective. Describe a system and ask it to list all the possible states as well as the state transitions.
Example diagrams
  1. 1

    Write a prompt describing the states and state transitions

    A simple one-liner can work too but the best prompts are usually at least 3-4 sentences long. Applying the below framework generally yields good results:

    • Make sure to describe states (e.g. logged in, logged out) and transitions (e.g. submit credentials, session expiry).
    • Include the visual requirements of a state diagram to the prompt: “States are circle shapes. And connections represent the transition between states. Use icons as appropriate.”
  2. 2

    Generate a diagram with the completed prompt

  3. 3

    Edit the diagram with follow-up prompts (this step requires signing in to Eraser)

  4. 4

    Manually adjust the layout using GUI controls (this step requires signing into Eraser)
