When D3 was released in February 2011, it transformed how we build data visualizations for the web and ushered in a new age of unbridled creativity in information design, data journalism, and beyond. Today, it remains the backbone of modern, interactive data viz.

Happy 15th birthday, D3 šŸŽ‚

There’s a South Korean middle school science teacher that’s been making free interactive science simulations on the web since 1996

He has hundreds of simulations now and gets millions of views per year. He was also named "Science Teacher of the Year" by the Korean government

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

ā€œSearching for Birdsā€ 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.

Indeed, very well done.
I find it interesting how many of the data visusalisation people are close together, but I’m somewhere far away between ā€œGerman-Speaking-Left-Wing Creativesā€ and ā€œGerman Digital Humanities Scholarsā€.

The optimist vs pessimist divide in #climate debates isn’t usually about the data.

It’s about how the same graphs are read, what people emphasise, what they discount, and how they interpret pace and stakes.

Here’s what I mean šŸ§µšŸ‘‡

Nature Cover Lost Science by Kim Albrecht

Nature Cover Lost Science by Kim Albrecht

In collaboration with Nature, I investigated the impact of the Trump administration on US science one year after its return to office. More than 7800 research grants were cancelled or frozen, affecting ~25000 scientists and research staff and resulting in an ~US$32 billion in lost research funding.

Thanks for keeping your reset up to date and for including a changelog at the bottom!

One small improvement that would have saved me from some moments of confusion could be to add an ā€œUpdated atā€ information next to the original publication date at the top of the post.

I agree with everything in your blog post.

The idea behind the icons in the ā€œSafariā€ menu *could be* to have one for items that can also be accessed via a shortcut, i.e. an important action. Except for ā€œServicesā€ and ā€œShow allā€. So it’s rather a vague theory.

I find those functionalities especially useful if the user can specifically filter the feed to their interests.

miniflux.app lets you filter items by Regex, but I guess that’s not for everyone.

I would like to strengthen the idea to not limit RSS to blogs. Podcasts are a good example of this flexibility. In some projects, we have implemented feeds for new (data) releases, status changes and other listings.

Wonderful to have a Svelte meetup in Berlin!
Thanks to @fubits.dev and @peterkogo.bsky.social for organising it, and to @dominikg.dev for coming over. Thanks also to all three of you for presenting!
It was a great start, and hopefully there will be many more to come!

I’m happy to hear that!
For me, 2025 has definitely been the year of making technological decisions based not just on technical requirements, but also on the people behind them.

You might want to consider using UnoCSS by @antfu.me, given this: bsky.app/profile/jare...

I’ve been very happy with the Tailwind Preset that UnoCSS provides.

Using all the different services is a bit of an overload, but in some locations the results are not that useful, so a fallback.
For the temperature, I use the average in the end.

I use Notion because I can add extra notes, such as the manually measured water temperature and duration, from my phone.

It also requests additional location information from Google Geocoder and 3geonames. All of this information is then put into a Notion table. The edge function then triggers a rebuild of the website. Meanwhile, the shortcut formats an SMS message to send to my partner.

I have an iOS shortcut that collects the user’s location and the current weather, and sends this information to a Netlify edge function. The function then uses the geolocation to request additional weather information from OpenMeteo and WeatherAPI.
