Hi data nerds! 👋 Data visualization and storytelling make an interesting part of a data analyst/ data scientist's job. In today’s video, I’ll be walking you through some of the worst (and common) mistakes in data visualization I have encountered in my career. Designing an effective data visualization needs both art and science (perhaps more art than you would like to admit). With this video, I hope to help you avoid the most important mistakes that you might encounter daily at work, and how not to be fooled by those 😉.
I hope you enjoy this video 😄. Let me know if I missed any important mistakes in the comment below 👇

Hey data nerd, thank you for watching! 🙌🏽 Let me know if I missed any data viz mistakes below 👇
You will be very big one day. Mark my word! Keep up the excellent work. You are amazing.
Look for the Atlas of Economic Complexity, the best dashboard i've ever seen.
Thank you for the high quality of your videos, so interesting !
I would love to see a storytelling data visualization project. Keep up the great work!
Thank you!! Great to hear many of you are enthusiastic about this! I will keep this project idea in mind 🤗🙌
Yes, I'd love to create that type of visualization shown at 13:30 . Please make a video on it. Thank You.
Just a glance of perspective: much of the advice in the video is strongly recommended for business presentation, but most of the time, like in journalistic articles (for example), the "bad practices" are consciously used to reinforce biases or manipulate opinions. So when you see a bad visualization, think twice about its real intention.
Great video, thanks for putting this together! I’d love to learn more about the scrolling visualizations.
This is great, exactly what I need to know. Very comprehensive and precise at the same time.
Hi Thu Vu, great video as always!
I'm definitely interested in a story telling project
I love the content you make. A video about the scrolllynteller approach would be great for visualizations with a lot of information. And if you can focus it with python that would be fantastic.
Well done! That was very helpful... thank you for sharing!
I am so glad I found your channel! I am currently learning data analysis and visualization right now and your videos are such a big help! Keep it up! Such excellently done videos on this topic!
So glad to hear! Thank you for watching 😀🙌
Great video love the way you explain the things thank you so much 😊
Thank you for your information. most of case are the one i've really encountered in my life. this contents quite helful!!
Cảm ơn bạn vì những thông tin hữu ích. Mình đang trên quá trình chuyển ngành. Muôn vàn khó khăn vì ko có background về tech. Hi vọng kênh bạn sẽ phát triển và tiếp tục ra đời thêm nhiều video hay như này nữa.
Thank you! This video was realy helpfull. It would be great to see one more video about data visualization.
Great content as usual, Thu. Bedankt!
Thank you so much. This was very informative 🥰 New subscriber
Amazing video, super helpful. Thanks
very good information, thank you!
3:35 😂 I totally agree, Thu Vu 👏🏻
That's a beautiful topic indeed: giving the audience the opportunity to grasp the logic underlying a chart because that's actually what we all look at before we comprehend what's written/visualized. At the end of the day, we all want people to absorb ideas quickly.
Thanks for your great tutorials. It would be nice to make a storytelling visualization.
I already knew this ideas but it was great to see how you explained in a pleasant way. Your videos are awesome! 😎
Haha indeed, I felt like a lot things might be too obvious to talk about.. Thank you for watching Bruno 🙌🙏
Thank you so much. Your video is amazing. Keep going.
Super helpful video--thank you so much!
I just wanted to say that you are my inspiration. You motivate me to learn new things and to improve my skills.
Very helpful, thank you!
Excellent video! 🤩
Very impressive take on in Data related subjects. lovely accent. Thanks for sharing your valuable knowledge.
Thank you so much for it lovely comment 😊🙌
Rules 4 and 9 🙌🏼All too often I see visualizations with too much information and too much color. #LessIsMorePeople
Haha same here! Thank you for dropping by, Luke! 🤩🤗
Yes pls more on creating a story telling visualisation :)
Nice! Thank you for compiling all this information for us!!! Please make a video about Scrollytelling = )
Very informative thanks, and please make a tutorial video about how you made that last dynamic visualisation
Beautiful content and a beautiful analyst
Hey Thu Vu, great video!! Plus the book you mentioned at the beginning is gold, I read it twice and I use it with my mentees and also in my day to day analytics deck at work 🙂
Absolutely agree, it’s a great book. Glad to hear about your experience 🙌
Now I should start modifying my projects thank you dear
Sometimes as a ds enthusiast we tend to cramming all of our result, resulting in clutter and hard to read diagram, we like to overcomplicate things 🥲
Yeah.. Absolutely 😅
great as always.
Great video Thu Vu!
Great content.
Another great video! Love it!
Thank you Sophia ❤️❤️❤️
New subscriber here 👋. Can you please make more videos on R whether it's related to visualization or basics. Thank you for this useful content.
great video 😃 thanks you very much for this information
Thank you for checking it out! Glad you liked it 🤗🙌
Great explanation of best practices. Sometimes labels of axes are not necessarily good and having values in thee chart itself is much more effective like in bar charts with many bars.
Also what did you use to get the scrolling viz? This is very interesting 🤔
Great video girl!
Please, we are interested in storytelling data visualization as you showed at the end (13:30) 😍 btw amazing video, love it and the book as well!
Great! Let me first think about a story to tell 😅🙌
My Professor once told us stay away from 3D scatterplots because the big idea is not communicated to the Audience. As you said: “it just looks cool”
I was pretty sad cause I made this cool 3D plot in R but I know he was right 🤣
Hahhaa I know that feeling 🥲😅. But can I see your 3D plot somewhere? 🤩
This is exactly what I needed haha
Data analytics is unexpectedly so hard for me lmao
Great great video!!! I am highly interested in watching a video of yours where you make a project from the scratch!!! I discovered your channel a few days ago and I can't get enough of it!!! Keep it up and tks a lot!!
Thank you so so much Mauro 💕🙌
@@Thuvu5 my pleasure, dear!
Không hiểu hết nội dung video nhưng giọng bạn càng ngày càng hay nhỉ? ❤
This video, it brings tears of joy to my data visualization eyes. haha
This is brilliant content. Thank you. Would you consider making future videos longer in duration by slowing down?
Thank you Jason! Yeah I was also a bit worried that the video is too fast-paced. I’ll keep your suggestion in mind 🙌🤗
Thanks for the video! Many people using border radius for the columns in column chart, is this correct to do that?
6:20 To emphasize this problem you can also show as example a paragraph where each letter has a different color, it’s not totally honest but it’s a very shocking image for the viewer. ^^
LOL that’s true 🧐😅
Hello would you say that Excel is one of the top software programs to use when analysing data?
Good video, thanks - summed up a lot of the points I was making to someone today, so I could have saved myself some time!
Could I make a plea on accessibility? Drop the music - it’s really distracting and makes it difficult to follow your points, especially for people with hearing problems (ie anyone over 30 😅). Just as with white space on a page, a bit of a gap between sections would really help!
Haha thank you for this feedback Jonathan! That makes a lot of sense! I’ll keep that in mind for other videos 🙌🙏
Chị làm thêm về data visualization tại (13:30) đi ạ, nó quá "cool" luôn ấy !
Would be cool if there was a space where we could share charts and graphs to inspire and receive feedback from each other.
@2:48 Killer!! 🤣🤣 poor stakeholders!!
Hi. Can you put the link to the image/ website that you mentioned at @3:55?
Hi Thu Vu! I am interested in the scrolling data story telling. How? 😁
such a gorgeous data nerd 🤓🤓
Hello Thu Vu! Great videos. We're flattered you've shared a dashboard and video (the eye-tracking) from the Big Book of Dashboards - could you please add a credit in your notes and a popout on the video? Thank you!
Yes sure! I’ll add that in. I’m sorry that I missed the link. Thank you for checking out the vid 🙏😊
Cảm ơn chị rất nhiều vì chiếc video ''hay ho'' này ạ :)))
Chị cám ơn em ❤️
10:29 that's how i make my presentation. It's almost as if i made that. 😂
I love complex charts! Am I not a normal human?
No you are not 🤖🤣
💫💫💫
Why so cute data scientist?? 😅
Moving screens & talking way too fast. It would be more helpful if u slow down a bit.
Thank you for the comment. I also realized that only after I finished editing the video 😅 Sorry for that, hope that the other videos are more well-paced.
