shuakami paperchart — timeline
Rows are tracks (team, workstream, service). Within a row, spans sit on a shared time axis; one span per row can be accented, and per-row milestone markers sit above the axis with a short label.
When to use
- Product roadmaps or quarterly plans.
- Release history showing overlapping workstreams.
- Migration timelines showing cut-over points.
