Which feature allows users to visualize project timelines in Smartsheet?

The feature that allows users to visualize project timelines in Smartsheet is the Gantt chart. Gantt charts are specifically designed to display project schedules, showing tasks or activities along a timeline. Each task is represented as a horizontal bar, with the length of the bar indicating the duration of the task. This visual representation helps project managers, teams, and stakeholders see the start and end dates, overlaps, and dependencies between tasks, making it easier to track overall project progress and manage timelines effectively.

While other views like Calendar view provide a different perspective on scheduling and can show when tasks are scheduled, they do not present the timeline aspect with the same level of detail and dependency tracking as Gantt charts. Card view is more suitable for visualizing tasks as cards within a Kanban framework, and Grid view offers a structured list format that is great for data entry and organization but lacks the visual timeline aspect. Thus, the Gantt chart is the most appropriate and effective tool for visualizing project timelines in Smartsheet.
