Same notion for Regular and Occasional Posters, but regarding Posting or Commenting in Forums.

The <a href="http://www.educationaldatamining.org/EDM2016/proceedings/paper_63.pdf" target="_blank">Video Interactions</a>
chart shows the average learner's sequential watching activity across videos. Each node (circle)
represents a <i>video</i>, and they are ordered according to the course structure. Each link (arc) shows the
the following video watched, and the thickness is proportional to the amount of students going to that video.

The <a href="http://www.educationaldatamining.org/EDM2016/proceedings/paper_63.pdf" target="_blank">Learning Path</a>
chart shows the average learner's sequential movement between course components during a given week.
Each node (circle) is a <i>type</i> of course component, and each link (arrow) shows the
<i>likelihood</i> that a student will transition from one event type to another.
The paths are calculated as a <a href="https://en.wikipedia.org/wiki/Markov_chain" target="_blank">Markov Chain</a>,
so the probability that a student goes to a given component type depends only on the previous component.
