# Timelines

> Roadmaps, changelogs and chronological sequences.

- [Order Tracker](https://www.assembli.design/components/order-tracker.md): Delivery progress drawn as a winding route: the line fills as the parcel advances, a truck rides the exact path between stops, and the active stop pulses. Fully driven by one current-step prop.
- [Gantt Chart](https://www.assembli.design/components/gantt-chart.md): An interactive project timeline: drag bars to reschedule, pull their edges to resize, everything snaps to days. Finish-to-start dependency arrows reroute live and flag conflicts with a dashed line and a warning icon. Today marker, weekend shading, keyboard control and a live summary.
- [Changelog Timeline](https://www.assembli.design/components/changelog-timeline.md): Changelog with a sticky date column and a rail that fills as you scroll. Release nodes light up when reached; entries are tagged New, Improved or Fixed.
- [Orbital Timeline](https://www.assembli.design/components/orbital-timeline.md): Roadmap milestones orbiting a pulsing core. Selecting one pauses the orbit, draws lines to related milestones and opens a detail card with status and progress. The orbit is pure CSS, nodes counter-rotate to stay upright, and Escape closes.
