This guide walks you through the complete process of creating an Excalidraw diagram using this skill—from understanding your content to delivering a polished visual.

Overview

Creating a diagram isn’t just about drawing shapes. It’s about arguing visually—showing relationships, causality, and flow that words alone can’t express. Follow this workflow to ensure your diagrams teach and communicate effectively.

Quality Checklist

Before considering your diagram complete, verify:

For Technical Diagrams

  • ✅ Research done: actual specs, formats, event names looked up
  • ✅ Evidence artifacts: code snippets, JSON examples, or real data included
  • ✅ Multi-zoom: has summary flow + section boundaries + detail
  • ✅ Concrete over abstract: real content shown, not just labeled boxes
  • ✅ Educational value: someone could learn something concrete from this

For All Diagrams

  • ✅ Isomorphism: each visual structure mirrors its concept’s behavior
  • ✅ Argument: diagram SHOWS something text alone couldn’t
  • ✅ Variety: each major concept uses a different visual pattern
  • ✅ Minimal containers: less than 30% of text elements are in boxes
  • ✅ Connections: every relationship has an arrow or line
  • ✅ Flow: clear visual path for the eye to follow
  • ✅ Rendered & validated: PNG generated, visually inspected, issues fixed
