This timeline template groups events into Early years and Growth sections — a pattern that works for product roadmaps by era or company history.

Swap years and labels for your own chronology; Timeline stays Preview-only in SayDiagram (no Arrange canvas).

Open the template, then Present the full timeline as a single slide or edit the Mermaid source directly.
