Information design and data visualisation. Cares about the climate crisis, post-digital media and technological justice. I like code and smoothies. https://links.jonasparnow.com 📍Berlin

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

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

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?

How clear and simple data visualizations bring the climate crisis home

Climate change is a slow-moving disaster. We need graphics that capture both its pace and its impact.

I'm very pleased to share Tunnel & Fortress, a new live coached training series bringing the art of system administration to those with no prior experience in the field. Participants will deploy, garden & harden servers to keep their communities safe. video.nikau.io/w/sXj2kQ8vQo... #exitbigtech

Introducing Tunnel and Fortress

A brief introduction to the new Tunnel and Fortress training series, hosted by Nīkau, and instructed by Julian Oliver. Please see here for more information: https://learn.nikau.io

I’m thrilled to bring together two institutions that shaped my work: BarabásiLab & metaLAB (at) Harvard. On June 11–12, 2025, we’re hosting Data | Art—a conference on how data entangles with artistic, scientific & curatorial practices. We have a stellar lineup of speakers! More soon: data-art.info

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.
