How to Make a Timeline

Timeline charts presents events and time periods on a chronological scale. They are used in project management to visualize project milestones and upper level phases, and show project progress.
"Within the framework of project management, a milestone is an event that receives special attention. It is often put at the end of a stage to mark the completion of a work package or phase. Milestones can be put before the end of a phase so that corrective actions can be taken, if problems arise, and the deliverable can be completed on time.
In addition to signaling the completion of a key deliverable, a milestone may also signify an important decision or the derivation of a critical piece of information, which outlines or affects the future of a project. In this sense, a milestone not only signifies distance traveled (key stages in a project) but also indicates direction of travel since key decisions made at milestones may alter the route through the project plan."

This timeline diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Timeline Diagrams solution from the Management area of ConceptDraw Solution Park.

The vector stencils library "Timelines and milestones" contains 24 shapes of time scales with start and finish dates, time interval bars with progress indication and brackets, milestone, event and today markers for drawing the timeline diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A timeline is a way of displaying a list of events in chronological order, sometimes described as a project artifact. It is typically a graphic design showing a long bar labelled with dates alongside itself and (usually) events labelled on points where they would have happened. ...
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." [Timeline. Wikipedia]

"Vehicular Ad Hoc Networks (VANETs) are created by applying the principles of mobile ad hoc networks (MANETs) - the spontaneous creation of a wireless network for data exchange - to the domain of vehicles. They are a key component of intelligent transportation systems (ITS).
While, in the early 2000s, VANETs were seen as a mere one-to-one application of MANET principles, they have since then developed into a field of research in their own right. By 2015, the term VANET became mostly synonymous with the more generic term inter-vehicle communication (IVC), although the focus remains on the aspect of spontaneous networking, much less on the use of infrastructure like Road Side Units (RSUs) or cellular networks."

This area chart sample shows the US federal prisoner population changes from 1914 to 2010.
"The Federal Bureau of Prisons (BOP) is a United States federal law enforcement agency. A subdivision of the U.S. Department of Justice, the Bureau is responsible for the administration of the federal prison system. The system also handles prisoners who committed acts considered felonies under the District of Columbia's law. The Bureau was established in 1930 to provide more progressive and humane care for federal inmates, to professionalize the prison service, and to ensure consistent and centralized administration of the 11 federal prisons in operation at the time.
According to its official web site, the Bureau consists of more than 116 institutions, six regional offices, its headquarters office in Washington, D.C., two staff training centers, and 22 community corrections offices, and is responsible for the custody and care of approximately 210,000 federal offenders. Approximately 82 percent of these inmates are confined in Bureau-operated correctional facilities or detention centers. The remainder are confined through agreements with state and local governments or through contracts with privately operated community corrections centers, detention centers, prisons, and juvenile facilities."
