I really enjoyed the course. There are many links to additional material so you can explore as far as you want. All R code used in the videos is downloadable and can be run side-by-side in R Studio. Instructor is very knowledgeable and material is organized well.

The explanations were clear, all the downloadable codes worked properly, the given links contained a lot of information (I won't continue with the next part of specialization until I could go through and practice them).

I am a veterinarian and based on the course was able to create visualizations on my own working fields (poultry production and epidemiology) as well.

In summary I found the course really practical and useful, thank you for it.

The course is very interesting. It helped me improve my skills with different graphs and charts

The best course that I took on Coursera. Thanks Prof. Collin Paschall very much for the entire course set up.

I really liked this course; Colin takes you through things step by step but also refers back to skills (data wrangling in this case) that were covered in the previous course. I found this reinforcement very useful as there is normally a bit of a gap between courses in my case. The course is well organised and all the links to the supporting materials worked and they added to the course, in my opinion. I would definetely recommend it.

The course brings me new practical and helpful information and knowledge, I like it much. Even though I had some previous practical knowledge about the ggplot package, this course force me to do some progress. Many thanks to Collin Paschall for his excellent video presentation and the staff who design and administer the course. I appreciate highly the possibility to use the advantage of learning from this course.

Excellent - the instructor Colin Paschall is clear and easy to follow, and the supporting materials (the code used in the lecturs, the transcript of the lecture notes) is also accessible and helpful. THANKS

so useful and practical for reseachers in social sciences!

the course helps me quickly grab the idea of ggplot and review the skills of data visualization :)

great tutorials, thanks a lot!

Es un curso excelente. Te brinda todas las herramientas para comprender la creación de gráficos con ggplot2. Sin duda alguna mis reportes académicos y laborales mejorarán completamente.

I used several times ggplot2 package in R but every times I should google how it's work. After finishing this course I had the feeling that I really know how to use ggplot2 properly.

Excellent introduction to ggplot capabilites and grammar of graphics. Usually the tutorials and ggplot documentation are not enough to reveal it's true potential.

buen curso, aunque me gustaría que metieran más fuentes, ya que serviría para aprender mejor

My best thanks to Coursera and Johns Hopkins University for holding this valuable course.

Excellent course, learned a lot; looking forward to the next one in the series.

Very nice course. I love how simple and straightforwad is the learning process
