This editor allows one to build interactive timelines. Right click anywhere in the diagram to add a new Event or Range node. Select an element to edit its properties.

Data formatted properly in rows and columns in either .csv or Google Sheet format can be imported using the File menu. A png of the entire timeline may be exported via the File menu.

Timeline data can be saved or loaded to or from various cloud storage services via the Open, Remove, Save, and Save As buttons in the File menu.
