A timeline is a graphical representation of a chronological sequence of events, often used to illustrate the order in which events occurred. Timelines can be applied in various fields, including history, project management, and education, helping to visualize the progression of time and the relationships between events. In project management, timelines are essential for planning and tracking the progress of tasks and milestones. They provide a clear overview of deadlines and dependencies, enabling teams to stay organized and focused on their goals. Timelines can be created using various tools, from simple charts to sophisticated software applications.
