flow family
funnel
Stage-to-stage conversion across an ordered process.
Each stage is wider than the next, encoding dropoff. Sales pipelines, signup funnels, marketing journey conversion. Reads as "100 → 60 → 25 → 8".
When to use
Sequential process with conversion at each step. 3–6 stages typical.
When NOT to use
No real ordering exists (pyramid layers without sequence) — use pyramid or bar.

Disambiguation rules
- Stages get progressively narrower, ordered (top → bottom or left → right).
- If shape is symmetric and bars are population-based (M/F), it is pyramid.
