A timeline is a display of a list of events in chronological order.
It is typically a graphic design showing a long bar labelled with
dates alongside itself and usually events.

Types There are different types of timelines
Text timelines, labeled as text Number timelines, the labels are numbers, commonly line graphs Interactive, clickable, zoomable
There are many methods of visualizations for timelines. Historically,
timelines were static images and generally drawn or printed on paper.
Timelines relied heavily on graphic design, and the ability of the
artist to visualize the data.
Timelines, no longer constrained by previous space and functional
limitations, are now digital and interactive, generally created with

Main article: List of timelines Timelines are often used in education to help students and researchers with understanding the order or chronology of historical events and trends for a subject. When showing time on a specific scale on an axis, a timeline can be used to visualize time lapses between events, durations (such as lifetimes or wars), and the simultaneity or overlap of spans and events. In historical studies Timelines are particularly useful for studying history, as they convey a sense of change over time. Wars and social movements are often shown as timelines. Timelines are also useful for biographies. Examples include:
In natural sciences Timelines are also used in the natural world and sciences, for subjects such as astronomy, biology, and geology:
In project management Another type of timeline is used for project management. In these cases, timelines are used to help team members to know what milestones need to be achieved and under what time schedule. For example, in the case of establishing a project timeline in the implementation phase of the life cycle of a computer system.
