Timeline from Si Digital. This time, the timeline is displayed horizontally! worth checking out.
What I like the most about this timeline from Mixpanel are (the vertical time line with years, the events cards, the categories' icons at the bottom of each card, and the actual date)
Awesome Timeline for Employees from Felix. The layout is broken into 3 columns where the middle represent the actual timeline and the side columns show the events. (notice the small clock at the far sides? Neat!
