Gantt with dependencies, progress and a late link — A launch plan: phases as rows, dependencies as arrows.

Dependencies are drawn as arrows. When a task starts before the task it depends on has finished, its arrow turns red and dashed.
Progress fills the bar.
Zero-length events render as milestones.

The demo runs a Gantt chart and a Kanban board over the same Task model.
