Indiana University is offering an Info Vis MOOC now (started Jan. 22)
The material is mosty scientific and network data. The goals are fit to match. The course is part theory, part skills, part client component, and has some questionable privacy policies. But for those interesting in learning a few techniques tecnhiques and exploring a MOOC from the inside (a.k.a. getting the student perspective), the course may be interesting.
So far, it has been for me.
