What is a timeline chart?
Timeline charts are highly versatile visual charts that are used to illustrate a set of events chronologically. They're an excellent tool for conceptualizing event sequences or processes to gain insights into the nuances of a project. That could include summarizing historical events, or any other time frame where you need to measure minutes, hours, dates, or years.
