The course with the IBM Lab is a very good way to learn and practice. The tools we've learned in this module can supply a good material to enrich all data work that need to be presented in a nice way.

Great course, one of the best course to get hands-on learning for Data Visualization with Python. Particularly the lap exercise, it will make you think on every line of code you write. Excellent!!!

Terrible IT support. Labs do not work. Never recommend IBM courses to anyone.

I completed entire program and received the Professional Certificate. On the Coursera link of my certificate "3 weeks of study, 2-3 hours/week average per course" is written. This information is not correct at all, it takes approximately 3 times of that time on average! I informed Coursera about it but no correction was made. It should be corrected with "it takes approximately 19 hours study per course" or "Approx. 10 months to complete Suggested 4 hours/week for the Professional Certificate".
Here is the approximate duration for each course can be found one by one clicking the webpages of the courses in the professional certificate webpage: (*)
Course 1: approximately 9 hours to complete
Course 2: approximately 16 hours to complete
Course 3: approximately 9 hours to complete
Course 4: approximately 22 hours to complete
Course 5: approximately 14 hours to complete
Course 6: approximately 16 hours to complete
Course 7: approximately 16 hours to complete
Course 8: approximately 20 hours to complete
Course 9: approximately 47 hours to complete
This makes in total approximately 169 hours to complete the Professional Certificate. As there are 9 courses, each course takes approximately 19 hours (=169/9) to complete.

Honestly, this is the WORST course I have ever taken on Coursera. And Alex Aklson is the worst instructor. As a course on data visualization, it should focus primarily on how to VISUALIZE the data. In other words, when we have the processed and formated data, how can we turn it into plots. But in the videos, especially week 2, the instructor over and over again repeated the data processing for Canadian immigration. After watching the videos, what I remember most clearly is not how to make the plots but the total number of immigrants to Canada from each country. And for the most important part, that is, the details of how to generate the plots as well as applying various features, the instructor just spent very little time in the videos. Yes, a lot of them are covered in the lab, but remember that for a course, the lab should just be supplementary of the lecture. The instructor should teach those skills systematically in the VIDEOS, and the lab should only be used to reinforce our understanding of those skills. In particular, as has been mentioned in many comments, the final assessment requires using the artist layer which was only introduced a little bit in the lecture but NEVER taught in detail. This is not responsible behavior. Overall, I am very disappointed. And I hope that IBM can ask another instructor other than Alex Aklson to create a new version of this course.

Very disappointing. Unfortunately, one of the worst course of the IBM Data Science professional certificate. It does not have the typical quality standards of an IBM course:
- Most of the videos are very short and do not go in the detail of the topic
- Videos have bad quality audio
- Labs are not laboratories where you use what you have learned, but the real lessons (without a deep explanation of what is done and why).
- Labs are also unbelievably full of typos.
- Most of the final assignment requires things that are not explained.
- The course also lacks consistency: they explain something and request totally something else regarding Data Visualisation (that you have to search on google).
- It should be a longer course, with longer videos that explain in detail how to make the various diagrams
I hope IBM will make a massive restyle of this course.
Do not attend the course if you are not obliged (you are studying for the IBM data science certificate).

Короткие лекции по 1-2 минуте вызывают удивление - неужто в IBM настолько разленились, что им языком лень ворочать?
В видео показывают и говорят одно, а в контрольных заданиях совсем другое, такое впечатлении, что готовит лекции один человек, а задания к ней совершенно другой и при этом они между собой не общаются.
Куча потерянного времени, раздражения и неудовлетворения, практических знаний - около 5% всего, в места 100%.

This is worst course in the specialization. None of the videos give any defined explanation about the parameters or keywords that are discussed in the labs. In the labs too there are no clear explanations as to why certain parameters are used. This is the worst course. I would recommend replacing the videos with videos that actually contain clear explanations. This is not for beginners.

502 Bad Gateway
The server returned an invalid or incomplete response.
I think, you really should change this course in a way that one is not dependent on labs.cognitiveclass.ai
It simply does not work. I have manually to upload everything to my light version of the Watson Studio.

The class itself is very high level (and super repetitive on unimportant information) , but the final assignment asks for things that were never covered in the class. Anything I learned from this I taught myself. Very frustrating!

This course is a disaster. Nothing works. It is impossible to propperly prepare the tasks because not one single lab is working. I am paying for this and I feel cheated. I am truly considering dropping from coursera.

I can't use IBM skill network labs for almost a week. There is always an error starting a lab and I will not go on course.
