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 🎂 d3js.org

📣 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.

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 🧵👇

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.

Data visualizations are some of the most powerful tools in a climate science communicator’s playbook. However, designing visuals that are clear to the public and policy makers is not a straightforward task, writes @rachitdubey.bsky.social . So, what works?

Lovely example of how weird real-world data is. I put all 55 million points in Overture maps into a Nomic Atlas map. Lots of points spuriously appearing in the ocean. But the 1° square around 'null island' (0° lat, 0° long) is suspiciously clear -- someone has cleared out bad data just there.

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography
This image shows the hourglass shape of the nights shortening and
lengthening from winter to summer and from summer to winter, passing
clouds, the Moon passing through the night sky every month (diagonal
bands) and the Sun climbing higher in the sky during summer.
