I took the course ISyE 601: Interactive Data Visualization last semester and I highly recommend it if it’s offered again. The class teaches you data analytic techniques and graphing methods for the datasets you create. The course was well-paced but you still get a lot of information out of it because it emphasizes human factor visualization techniques too (it fulfills the IE Human Factors elective). It seems very similar to the 412 project but the class is in R instead so you’ll get to learn another language too.
I’m unfamiliar with any course in the Stats department that would be similar to the material in 412. I believe most of the classes offered revolve around R but they stick to the mathematical side of it, not the visualization aspects. If you want to strengthen your R skills though, they offer 3 1-credit courses over the length of the semester.
It actually does look like ISyE 601: Interactive Data Visualization is being offered for Fall 2019. The lectures take place T, TH 9:30-10:45 am in ME and are taught by John Lee. I was able to find it in the Course Guide as well as Course Search & Enroll in MyUW. I also spoke with Professor Liu about courses after ISyE 412, and he said he teaches ISyE 691, which covers similar information but goes more into detail. However, I am not sure if 691 is offered every semester.
