What type of chart is commonly used to visualize the timeline and progress of tasks in project management?

A Gantt chart is commonly used in project management to visualize the timeline and progress of tasks. It provides a clear visual representation of the project schedule by displaying tasks on the y-axis and time intervals on the x-axis. Each task is represented as a horizontal bar that spans the duration of the task. This allows project managers to see at a glance which tasks are scheduled for which periods, how long each task will take, and how tasks overlap or depend on one another.

Gantt charts are particularly useful for tracking progress because the bars can be updated to reflect the completion percentage of each task. This real-time visualization helps teams manage resources effectively and adhere to deadlines by providing a straightforward view of the project timeline.

In contrast, a PERT chart focuses more on the relationships and dependencies between tasks rather than their timelines, while a flow chart represents processes or workflows in a more general format, illustrating steps and the flow of information. A sequence diagram, on the other hand, is used mainly in software engineering to detail interactions between objects over time, which is not specifically designed for project scheduling.
