I was a very difficult course for me but it was very instructive, I understood some of my weakness in Python and OOP so I need to work on that, now I know data visualization is a major topic in DS.

By the way, Google was a very useful tool to review new concepts for me and get ideas how to approach the problems.

Using python to create graphs and charts is very simple and easy, once u remember all the basic and keep trying. It seems to me that it is easier than any other reporting tools I used before. It is great that I know where to find the tool to create these charts and graphs if I need to prepare presentation. :)

Though the course videos were short, giving an introduction to how different charts look and to plot them, the lab sessions were the best and gave a plethora of information on data visualization. Also, I am glad that they included the folium part of the course in the assignments which were very well formed.

Nice lecturer and useful tools. This course was really interesting though pretty hard for me. Sadly at the end of the course I didn't feel that I gained enough skills to do the lab easily but maybe it just me. Anyway I ll definetely return to this course again to get the better understanding of some topics.

This is by far the most understandable and well explained course so far in this IBM Data science, this is what we call beginner friendly, , step by step explanation, repetition and clarification to make sure the students follows and understand, i wish all instructors were like this. I strongly recommend .

I really enjoyed this course! The labs used interesting, real-life data and did a good job explaining the purpose of each line of code in an easy-to-understand way. I appreciated the questions in the lab because they built on and stretched my understanding of Python from past courses. Thank you, Alex.

Really nice course. This course has helped me build up a number of Data Visualization skills, and I am able to draw meaning and conclusions from data easily and much faster. The course labs are excellent and the final assignment was a good way to test the skills that I developed during this course!

I feel this is harder than the other ones in the series, sometimes you need to google a little bit to figure it out.

I spend more time for a week, but I wonder why I have to do it in Python. I learn Python just for faster loops than R. Personally I think R need less coding and produce better graphs.

This is one of the most interesting courses from Data Science Certificate so far. Everything learned in this course is very important for a data scientist, aand the best thing is that there are several hands-on activities to do. I really honed my data visualization skills and expanded my toolbox.

This is a very enjoyable course, even though I was familiar with most of the tools, I still got to learn a few new tricks. If you are not familiar with programming, you might find the final assignment a bit challenging. Therefore, I strongly recommend that you take the course labs very seriously.

Course is really good to learn all the fundamentals of data visualization along with the advance techniques to master it. Assignments and practices are designed very well by the instructors and you would have to put all your efforts to understand and master all the course. Kudos to the IBM team

Best course so far in the series. The labs are great, they make you really apply what you've learned.

The final assignment is a true test of your skill. You can't repeat what you've done in the labs or what you've seen in the videos. Perfect test of skill. I've learned a lot.

Thanks Alex Aklson.

The final assignment is excellent! It is not just straightforward but requires us to think and research, go beyond the basics learnt in this course. Amazing course! Just the right amount of videos, simple labs, and challenging yet effective assignment, I learnt a lot! Thank you Alex Aklson <3

This course consist of most of plotting types with python, it's not only about matplotlib, but addtional tools and methods to create maps. It gives you a fabulous understanding about visualization using python. Completing this course, you will be able to demonstrate the data in ways you want.

Liked how it covered a vast amount of topic related to data virtualization. The notebooks are really useful for taking help in future works. I did like too see more details explanation and practice problems related to the libraries used in the notebook exercises. Overall loved this course.

Though the videos were short and running fast the labs were well designed, the peer graded assignment is well prepared too. I feel more accomplished than before. Honestly, this course should've been suggested to be taken at least before 2 other courses that I already finished to get here.

Exceptional Course, Cover all Point regarding Visualization. Far better than, my expectations. All assignments are great, and those who completed each and every assignment by themselves will learn a lot of things from them. Had a great learning from this Course. Thank you, IBM for this.

It was very good and interesting how to create different kinds of maps for different purposes, specially I liked the maps that you can embed in an image like the wordcloud using a mask from Alice in Wonderland, I will try to do something similar with another topic. Thank you very much.

Course is very good. I have advice for learner to pay attention to each week videos,, especially Week 5. Final exam is tricky exam. Otherwise course is well design. Only complain, lab is availability is unreliable. I had to switch to local jupyter notebook. Otherwise good luck to all

I appreciate the way the Instructor always (always!) refer back to previous lessons, so that the transition to the next lesson becomes seamless. The lab also reviews past exercises so you are not at a lost (especially if you have not gone through the course for a while).

Content wise, the best course in IBM Data Science Professional Certificate, as the quiz, lab and assignment modules really tests your knowledge. It made me learn a lot apart from course content to earn the course completion. Kudos to the content creators Jay and Alex.

As I have no coding experience, it is hard for me to follow the course material. To finish the assignment, one have to repeat the exercises in the labs until one has everything understood and remembered. Not a easy course but it gave me a sense of fulfillments.

A well designed and executed course. Basics understanding of python is essential for this course. The course provides great learning to all those who watches all the videos, practice the ungraded assignments seriously and works through the course sincerely.

Excellent, this is a great course introducing and teaching visualization !

PS : You might read about people telling that some of the materials in the assignment is not in the course. It's false it's in the lab. These people should take notes while working.

Excellent Course. I would recommend that the first week of this course be included in the introductory courses in Panda analysis. It will allow the student to really see the value of Pandas over an Excel and provide more of a boost to learn quickly.
