Wondering if you can outsource your data viz work to ChatGPT? 📊

I tested out a few different generative AI tools, giving them prompts to visualise two different data sets. If you're interested in the results, you can read them here: nrennie.rbind.io/blog/gen-ai-...

Generative AI for Data Visualisation – Nicola Rennie

Can generative AI create good data visualisations? This blog post compares the performance of ChatGPT, Claude, Copilot, and Gemini when presented with a generic request to visualise a dataset.

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

📊 How can you turn data visualization into a community experience?

Nina Koch (@nk-yeahyeah.bsky.social) shares her insights and lessons from a fascinating, fast-paced workshop where participants co-created a datavis about their changing interests over time.

Do you know individuals who seem to focus on one thing for their whole life? I’m on the opposite side of the scale.

This article manages to name her husband before it names… her.

Article reads:
Woman named as Archbishop of Canterbury in historic first

The 63-year-old archbishop-designate is married to Eamonn Mullally, with whom she has two children. Originally from Woking in Surrey, she was the UK's chief nursing officer from 1999 to 2004.

It has minimal dependencies, supports for every output type I make (so no longer need to switch packages based on output type, including Typst), and every time I've used it it has "just worked".

So here it is: my dumb data viz experiment. 🍩

✔️ Solves the continuity problem
❌ Harder to spot patterns
❌ Hours are visually distorted

But hey… not everything has to be practical, sometimes it’s just fun! 😅 Also: how cool would it be to create a physical object like this?
