An UI for biographical timelines. github 
Elm Timelines is a user interface for the creation of timelines, written in Elm. You can use it e.g. as an aid for remembering your life. The special trait of Elm Timelines is that it deals with uncertainty. You're not required to enter exact dates but draw timespans within a timescale. If you're not (yet) certain about a timespan's begin or end you can add an uncertainty range. Elm Timelines visualizes this as "fade-in" resp. "fade-out" then.
