Create awesome timelines with TimelineJS

May 15, 2017

Organizing dates and events is a must when you want to tell meaningful stories. Narrating events like the Arab revolution or the crisis in Venezuela requires a lot of organization, especially when there are so many situations that arise and change rapidly.


Now, this challenge becomes even greater when you present these facts to an audience as part of a narrative.

To meet this challenge, the Knight Lab presents TimelineJS, an open source tool that allows anyone to construct visually rich and interactive timelines.

To do it, you just need an Excel sheet that follows this model and is made public on the Web.

However, if you want to add your personal touch you can modify the .JSON file to create custom installations, maintaining the main functionality of TimelineJS.

Among the things you should keep in mind to make the best timelines are to make short stories, no more than 20 slides, not make time jumps but keep a chronological order and include this piece as part of a larger narrative.

In Datasketch we've used Timeline JS to narrate how the Venezuelan crisis has evolved. Check it out here.
