Swimlane-flow roadmap

Produce a .drawio file with horizontal stage lanes stacked top→bottom: each lane is a colored rounded band of titled unit cards, wired by directional arrows that make learning order explicit. Best when sequence and prerequisites matter.

When to use

• This skill (swimlane) — strict order / prerequisites; each unit has title+subtitle; arrows show "learn A before B". Cleaner for courses.
• drawio-roadmap-snake — poster visual impact; many parallel items per category.

If unsure, ask which they want, or offer to produce both.
