Does the "keep up the momentum" graph count as a nonessential JS feature?

On occasion, the graph titled "keep up the momentum" at the end of each step doesn't load properly, or at all. Is this an example of an optional Javascript enhancement that enhances the page without being required, like is discussed in this video?

Yes, the graph is not essential. Not sure why it's not loading for you :(

But, this site is not designed with an unobtrusive approach. If you turn off javascript, you will not be able to watch the videos or view the courses content list. All that is delivered via javascript.

When a site or page must rely heavily on javascript to deliver essential content, the noscript tag should be used to instruct users to turn on their javascript.

If you replay the video, it doesn't show the graph.
