A project timeline is a list of tasks or activities organized by the date that allows project managers to see the entire project in one place. A project timeline is usually shown by a horizontal bar chart, with each task assigned a name and a start and end date. Timelines are becoming popular in projects (and products) because they give a good overview of the different activities and areas. They can be used to display events, products, designers and just about anything that plays an important role in your project. Timeline views are used extensively on social media and can provide a very engaging way of displaying information on your website.
