🎮 Can you spot the better chart?

👋 Hi!

I’m currently teaching data visualization with R and Python to over 1,000 people, and I absolutely love it! ❤️

Each course includes a Discord channel where students share their charts and get constructive feedback.

​
​A common struggle

Here’s something I’ve noticed: most students are great at coding, creative, and know the dataviz best practices.
​
But many still struggle with design.

They produce charts that are technically correct but not very pleasant to look at.
​
So what really makes the difference, once your plot is theoretically correct, between a polished, professional-looking chart and one that feels... off or untrustworthy?

​
​A little game to help

To tackle this, I created a simple dataviz design game.

Play the game now

​

You’ll see pairs of charts side-by-side and must choose which one looks better.
​
Each pair highlights one key design concept that can elevate your charts from “meh” to “wow.”
​
That's the first question:

Hopefully, this little game will help you elevate your design skills!

​

A shoutout

I got the idea from Can’t Unsee — a similar game focused on UI design that I’m a big fan of.

Thanks to Diana MacDonald for the original beautiful charts! I just created “degraded” versions of them and built the game around it. 🙏
​

Try it out and let me know

This is just the very first version, and I’m eager to hear your feedback.

Did you like it? What could be better? What design caveat is missing?
​
Please hit reply and share your thoughts! 🙏

See you next week,

PS: I love pushing the boundaries of online learning. If you like this game you'll love my R and Python dataviz courses!
