Good course but need some thing to do:

1. More material. Some topics are just looked superficially.

2. Need provide addition video lessons ore provide information to student that he need know some visualization tool. Excel, Tableau, any thing.

3. There is some errors what still not corrected for many months - in week 4 some video is empty, some misunderstanding information on video slide.

Too much background information, not enough information critical to applicable demands.

most horrible specialization in coursera! Time wasted

The lectures introduces various ways of visualizing data.

There are fewer details on Tableau software usage and hand-on network graphing tutorial, students will have to search for more knowledge in these parts during the class.

Very nice course. It encourages you to learn different data visualization tools for completing the assignments. And, peer graded assignments are too beneficial since, they give you a sight of how other peers are completing their work and all. Lecture videos too are awesome!!

Really like this course which leads me to Tableau. After the course, I take about 8 hours to learn Tableau and I think my ability of data visualization ballooned.

Good course, very well structured and with interesting assignments. Some (especially first) lessons are more of a general culture but most are very helpful and allow to learn a lot of things.

seemed to me the best course of the specialization

Very solid data visualization class for people interesting in visualization. It explains a lot of knowledge under the hood. Not that fit for people who just want to learn some tools and quick skills. It is computer science.

Bueno para obtener ideas de que hacer, pero necesitas saber programar a nivel basico

The fundamental concept part and assignments are good.

But I think since it is related to visualization, the course can spend more time on how to make a visual.

This knowledge is fantastic.

Excelent general concepts of data mining along with basic methodologies and applications, congratulations...¡¡¡

it is good.,

Interesting course for getting started with complex graphing principles. The instructor was easy to follo

Good course

Very good knowledge on visualization. Never though these many indepth concepts are involved in visualizations.

Ce cours est plein de connaissances utiles et permet d'acquérir un background important en matière de visualisation de données

I like it! Very useful!

I got a new type of understanding and importance of Data visualization

amazing

内容还是少了点，但是总体还是很不错的。

this is my first course from coursera and its very experance after taken this course

i an very bringnner this course help me lot to take further path towords the data science and data mining

thanks sir

Very enjoyable class. I especially enjoyed interactions with other classmates. And I learned a lot about data visualization!

Excellent Course. Give me a good understanding of how to visualize data to make it clear and fit the user's need. And the assignments is also useful. I learned how to use D3 to generate the data using Javascript and D3 library.
