The InteractiveTimeline extension allows users to insert timelines into wiki pages. The timelines are shown using the vis.js JavaScript library developed by Almende, so they may be panned and zoomed by the user, and events in the timeline may contain images, links to other wiki pages or sites, and other formatting. 

Full documentation may be found on the [extension page](https://www.mediawiki.org/wiki/Extension:InteractiveTimeline)
