Time.Graphics is the most complete tool to create timelines and organize comples series of events with different types of elements. It is user friendly and the interface is very easy to use. You just have to add and customize each event or element in a simple form where you can put the date or period, title, notes and decide the type of line, box or position. As a cumulative process, at the end you are just amazed by the visual result. The variety of customizable options allows you to create visual codes and make your timeline more effective. There are lots of options to download your timeline in different formats and also if you want only the data and notes, you can download all the input information in a xls file. It is just amazing. It has helped me to organize a complex literature review that included publications, exhibitons, tesis and historical events throughout a vast period of time. I love it.
