The course is good but I faced frustrating situations of not being able to run my code in the provided labs. I had to spend significant amount of time trying out several recommendations in the Discussion Forum and even outside the course material. I guess, this is part of the nature of a MOOC course of this nature.

This course is much more difficult than the previous courses of IBM Data Science Professional Certificate series. Lack of tips and procedures makes it a challenge both to follow the video and to finish the final assignment. However this is similar to the real environment where you have to solve problems yourself.

This course is great for those who want to learn the art of visualization in python using different packages available for python.The only thing I want to point out is that it is using outdated packages of some libraries.Once the assignments are updated with the latest libraries ,Then it will be a 5 start course

I enjoyed learning about Matplotlib, Seaborn, Plotly and Dash to create effective and attractive visuals. The videos were long enough and the practice was very helpful. I just think that in several occassions the study material was overly explanatory to the point of giving unnecesary and repetitive guidance.

Good work through the information. Assignment challenged your knowledge. Would have given 5 stars but I continually had issues with the Jupyter Notebook crashing. I had to restart the server or just leave it for a couple hours. The content was great, but Jupyter notebook frustrated me incredibly!

Excellent Instructor. One of the best in the series. Very clear explanations, and resourceful.

One suggestion - edit Question 4 of the final assignment so that a who student copy/pastes the instructor's image would not get more points than if they put in the code they did to try to get it.

This data visualization course teaches very basic graphs. Two good thing I came to know through this course are Folium and two layers in Matplotlib which was interesting. I was Expecting some more interactive graphs to learns by taking this course but the course disappointed me there.

The workload for lab is quite big compared to other learning component in this course.

The most difficult and time-consuming part in lab and assignment is not about the visualization, is about data processing. Suggest having a more structured data pre-processing summary at the front.

This course was thorough. However, we could have been prepared better for the final assignment. I had to rely on the internet a lot to complete it. I don't know if that was intentional. If it was, then it should have been stated explicitly. Otherwise, well done and thank you!

Hi

The course itself was interesting and helpful, but unlike other ones, most of it was based and dependent on labs. Unfortunately, due to the skills network lab environment problem, it was so tough to follow up the labs, and the most important one was the final assignment.

Extremely challenging final project. The specificity of how the bar graph was to be labeled was, quite frankly, maddening. I don't remember having encountered a single whiff in the course of how one should proceed with the labeling in the very middle column of a bar graph.

Course was very good, but uploading final assignment was a bit missleading, beacause you have no opportunity to show the whole dropdown menue with all the years included. There is always only a selection shown in browser. So screenshots to make aren t´the best solution.

Quite an extensive course - as a beginner it went a bit over my head at times. The Assignments were challenging and the final one was a bit dissapointing - not all the elements were covered in the labs so had to trawl the internet looking for answers. Learned alot though

Course is great but the part with Folium should be separate course (some Advanced Visualization) rather than graded part of this corse. Instead of using Folium in final project it would be better to use some Seaborn advanced visualizations or other plots in Matplotlib.

The most interesting course in the specialization up to now, for me at least. A brief but informative overview of all kind of plots that can be done on pandas dataframes.

To the course author: repeating the data wrangling/cleanup in EVERY video gets annoying.

Teh course went well. Would have liked to have seen more education on the DASH function definition under the input/output callback. Would have also liked to have seen more education sorting the data by month and then plotting by abbreviated month labels.

Although the content of this course is very interesting and has a lot of depth in the field, I believe that it needs further improvement, specifically with more examples in the labs, in order to get a better hang on the different types of visualizations.

The materials are OK, the labs are really helpful, but the test-related data files that needed are hard to get. In fact, some of the csvs required to complete the test are out of time, and students can only get the data through the forum, that's a pity.

Hey! Thanks for the course. At the beginning everything was good and understandable, but at the end of the course the teaching material was not sufficiently developed. In the laboratory, it is necessary to describe more actions and possible solutions.

Overall the content of this course was good. There were some headaches with getting folium working. It was annoying listening to the description of the dataset we've been using for half the video every video. But it did help with learning matplotlib

Short videos but well-worked notebooks with many examples on Visualizations with Python. Exercises had tricky questions that the student must pay attention. The final assignment is difficult, since it uses some features not explained in the classes.

It is a great learning experience, but if course staff can look into issues candidate face it will help them. But for me it was a challenge as am i am new to programming. Thanks to forums and of course Google and python community for big support.

While the course was very good and showed lots of different data visualizations available in Python, the final assignment required topics that were just briefly touched upon and required quite a bit of outside research to figure out the syntax

Mostly really good. great practical projects. would have liked a few more practice sets to better understand some of the unfamiliar concepts that popped up in final assignments, but other than that i really liked it, great helpful TA as well.

This course is interesting to learn and the final assignment is not something you can copy from the lab sessions and easily pass, which is good. However I noticed the questions posted on discussion forum are rarely answered by teaching staff.
