The world feels quite precarious right now—and sometimes we forget what it feels like to pursue happiness. @alv9n.com digs into a study that asked more than 10,000 people to share their joy. From personal growth to friends and family, here’s our happiness mapped.

Love it! A new creative take on the old topic of Olympic reporting 👍

We visualize the Olympic medal count as Norwegian-style scarf. :) 📊
Check out how Germany looks like and generate your own scarf – including download of the knitting pattern.

Is it DVS related? 🕵️

Back when I worked on iD (the default OpenStreetMap editor) I designed over 270 bespoke map icons to illustrate various feature types. These are free and open source.

A guided gallery of my icon work is now available on my portfolio: waysidemapping.org/projects/id-...

I feel like we are getting closer to that, let's try to make it a reality together. All of us. 😊

Finally giving Bluesky another go 🦋
I miss the good, old Twitter vibes of posting also the non-polished, in-progress ideas. And with a limited character count also actual short content and not a wall of (AI?) text
🤞

It's like the Marvel Universe, but for... Us?!

Count me in!

Wow, this is incredible! Very much looking forward to this :)

It's like Data Stories meets Explore Explain 😍

I was so fortunate yesterday to spend a superb 2 hours chatting with @moritzstefaner.bsky.social & @ebertini.bsky.social exploring some of the most significant data viz works that have shaped their careers. This will be released as a double 'Explore Explain' episode special out early next month.

Few life experiences feel as universal, across generations, as the pains and frustrations of trying to find clothes that fit. In our newest project we dive into the data about women's sizing chaos.

📣 NEW! I’ve just released the BIGGEST and perhaps most creative project I’ve ever worked on!

“Searching for Birds” searchingforbirds.visualcinnamon.com 🐤

A project, an article, an exploration that dives into the data that connects humans with birds, by looking at how we search for birds.

In case you missed it: my full, free, open course on accessibility and visualization is out!

Wow, that's great! It looks very smooth, as expected.

Thanks for sharing Moritz!

She has other amazing sets as well, but this one has a very special mix of genres, so I expect the visual representation to be interesting :)

NEW EPISODE!

What do cartoons have to do with data viz? More than you might think! I chat with @chazhutton.com to learn about this artform and the critical thinking that shapes this contrasting visual form.

Introducing ReliCSS: A Tool for Front-End Archaeology Introducing ReliCSS: a tool that helps you identify browser hacks and CSS artifacts in legacy codebases. Understand the 'why' behind old code and prioritise refactoring efforts.

a couple of weeks ago I 'launched' ReliCSS, an online tool to find those browser hacks you no longer need.

I wrote up a quick 'introducing' article:

Looks great! What do you use it for?

I just joined because people told me there was a good dataviz community on here. Hope to meet some of you soon!

I recently created a UI for working with orthographic projections of hypercubes. Try it out here:
