The map automatically pulls up a notable livestream that has a bunch of viewers, and also shows where a video is being watched using threads that connect a video visually with dots on the locations of its viewers.
Called Facebook's 'Live Map,' it's simple and straight forward to use -- pull it up and click on a blue dot.
Hover over it, and you'll get a small window as well as threads connecting other viewer's locations so you can get an idea of where people are watching.
The left-side pane shows a primary video — at this very moment, it s a Cosmo editor getting her first tattoo, if you re curious — as well as some other options below it that, when clicked on, will bring up the video.
It seems like the high-end of live viewers are topping out in the high-thousands, with the top video in the pane having about 8.5k viewers.
It's exactly what it sounds like -- a way to watch or broadcast live videos on Facebook's platform much like you'd find on Periscope.
