•I have been progressing through all the courses in this specialization and, overall, the courses have been of tremendous value to me. However, it's really not the courses themselves but the book that goes along with the courses that deserves the four and five star ratings I have previously given (these courses are really nothing more than "read the book" and "take the assignments"). Nevertheless, the knowledge gained is not easily available elsewhere. 80% of this visualization course (i.e. the book) was excellent and I give it top marks. The other 20%, starting with the grid system section to the end of the book, was terrible. These sections need a complete rewrite as they are barely comprehensible and certainly not comprehensive. The final assignment does not test you on how much you learned in the course, rather it tests you on how much time you spend on your own finding other relevant sources of information on the internet to figure it out. Also, I don't understand why creating a custom geom would be a more important software development skill than R Shiny for example, given that having the ability to develop interactive apps is critical to visualization. I will give this course 3 1/2 stars, rounded down to 3 since coursera won't allow a half star. I hope the authors take what I have to say as an opportunity for improvement since I have benefited tremendously from this specialization so far and I would like to see it improved in certain areas.

•This course was not good at all. Almost all of the information is a screen scrape from a book and peer-evaluated, so you may be better off just getting the book and going through it. Neither the mentors nor the authors ever participated. The assignments are poorly written and missing too much detail. Ending up bailing on the course and the final capstone as I'm simply not learning anything and the projects are too frustrating to work on.

•The course is just a dump of the recommended reading book. There are zero videos, zero walkthroughs and zero interaction with the instructors. The final project is over-demanding for the level of the content provided. I don't recommend this course to anyone.

•Great gap between teaching and what is required to pass the course. Unnecessarily difficult.
The didactic material is not compelling.
Not recommended.

•I could plot in R before and many of the topics discussed in this course I already had a working grasp on. Still, the course helped me really gave me a whole new depth of knowledge on the packages that plotting is build around in R. Highly recommended!

•This course introduced to me the advanced capabilities of data visualization in R, especially using GGPLOT. It was bit of a struggle in the course project as the examples in the Mastering Software development e-book were little simplistic in nature. Overall, very satisfied that I can create my own geom. The key learning was on creating visualization using spatial data.

•Like other courses in this mastering, it is a little bit outdated and the practical tests proposed are way harder than examples presented before, but still worth doing because of book, "getting hands dirty" and forum.
創建者 Antonio G
•Great course! You'll learn a lot about the graphic capabilities of R. However, I think there are some things that need to be explained before one goes on to complete the final project.
創建者 Mridul M
•It is a good course. The only downside is that if you are a beginner level R programmer and want to upskill, you will need to do an extensive search to complete this course.
創建者 Sandjaja B
•It is a very good course, but feels a bit more hands-off than the other 3 preceding courses in the Mastering Software Development in R certificate.
創建者 Francesco D Z
•very useful, especially the final practical exam.
not 5 score because I think more time should have been spent in more modern interactive charts

•So first of all, the material for this course in the bookdown document are very good - well structured, with good sources. My concern is that the Coursera course does not go a lot beyond, basically just referring to the document and adding quizzes + graded assignment in the last week. The assignment, however, is nice and challenging and requires people to understand the materials.
Also, the course covers other great packages than ggplot2, e.g. plotly and leaflet and methods for handling spatial data. I think it would be very nice if the students were challenged in these topics as well and evaluate them in a better way than just a quiz (programming assignment for instance).
I liked the course though and I believe it can be prepared even better.

•This course is not as satisfactory as the second one, "Advanced R Programming". You spend most of the time reading the book they wrote. There is no video lecture or interactive quiz. The most annoying part is the peer-reviewed assignment part. This is a coding project where you need to create your own geom. I understand that building your own geom is an advanced topic in visualization using R. However, at least for me, I rarely have this need in my work. The example and the dataset they use for the project isn't very interesting neither. Overall, I think this course should not be included in the specialization.

•Content on ggplot2 framework is solid. However, no video or explanation to complement the textbook, students are expected to learn by reading solely.
Final assignment requires prior R programming knowledge, which is not taught in this course. This can lead to frustration in the end. Probably those who are enrolled in the entire specialization will find this assignment more manageable. I personally had to spend more than 20 hours on this supposedly 4-hour assignment.
