I was looking over the Tensorflow.js dependencies and noticed that fbjs is included in the dependency list. What functionality requires fbjs? I'm not familiar with the package, but I'm aware that it is a Facebook JavaScript package. It just seems a little strange to me, but as I said, I don't know much about fbjs so maybe there's something useful in the context of Tensorflow.js.
The Facebook JavaScript package, fbjs, used in Tensorflow.js is for the tfjs-vis package. fbjs contains several visual tools utilized in tfjs-vis.
Being that Facebook is most known as a social media platform, I found it odd at the time.
