“Northwestern University Knight Lab’s TimelineJS is an open-source tool that enables anyone to build visually rich, interactive timelines. Beginners can create a timeline using nothing more than a Google spreadsheet, like the one we used for the Timeline above. Experts can use their JSON skills to create custom installations, while keeping TimelineJS’s core functionality.
Tips & tricks:

1. Keep it short. We recommend not having more than 20 slides for a reader to click through.
2. Pick stories that have a strong chronological narrative. It does not work well for stories that need to jump around in the timeline.
3. Write each event as a part of a larger narrative.
4. Include events that build up to major occurrences — not just the major events.”
