TimelineJS is a tool that helps create a timeline with various media content. It can also be described as an aggregator of online materials that pertain to a certain theme with a chronological time set.
TimelineJS can be useful for a number of purposes, especially for a digital humanist. Timeline allows one to create according to their project needs. It also proves a s useful tool for teaching and learning because of the level of interactive material that can be added and the visual aspect of it. Instead of just having a traditional timeline it allows users to get more information and explore that information to a great extent.
The video below shows one how to get started in order to create their own timeline (using a google spreadsheet) and the various media content that can be added.
I have included a screenshot that may help to understand exactly how the cells work:
