This is absolutely fascinating: you can put your postcode in and see relative levels of deprivation (and the opposite) where you live in detail. I live where I grew up, so I could spend days doing this as I know the town so well. www.ft.com/content/9a1c... Huge congrats to @amyborrett.ft.com et al.

Had a lot of fun coming up with a title for my #Quarto demo I presented at our internal learning sessions aka R-Cafes 😆 So here you go ... Quarto Macchiato ☕🥛 #Python #Rstats

Data in a csv format which we converted to a pdf which we printed which we then scanned which we embedded in a slide deck which we then encrypted which we lost the password to and cited as “available upon request”

This made me laugh! #UX in the wild. (Coffee machine at my local IKEA store) 😅

People in some areas of England and Wales are almost twice as likely to die before 75 (premature mortality). Out latest analysis shows rates are highest in the North East, the North West and Yorkshire and the Humber, and lowest in London (> Richmond) Learn more www.health.org.uk/reports-and-...

Last week I had the pleasure of finally releasing the #SveltePlot alpha version during my talk at the #SvelteSummit in Barcelona. It's a new visualization framework for @svelte.dev that I've been working on for the past 18 months, so it's about time for a 🧵

How much should #NHS staff be paid? Only 32% of NHS staff are satisfied with their pay, a relatively consistent trend. But what is the right rate for NHS jobs? How do you judge if people are over/underpaid? A thread based on our latest analysis 📊👇 1/ www.health.org.uk/reports-and-...

Better world maps for mobile! Despite years of mobile-first design, there’s been little experimentation in this area. So we designed our own at NZZ – and validated it in a large user study. Summary of the paper: jonasoesch.ch/articles/the... 1/3

I've been using the same data to mimic the chart style of @economist.com when they showed Elon Musk's tweets/posts. It involves using a day/hour summary table as well as the monthly counts to simulate individual attendances but I'm aiming for a more 'visceral' effect. #rstats #ggplot2

So, show-and-tell time… (this’ll be a thread, strap in folks!) Back in the day I used to draw a little cartoon whale on a post-it note…. It looked like this.

#30DayChartChallenge Day2 Slope – Google search interest in “How to remove Meta AI from Whatsapp”. As Meta AI’s chatbot is rolled out across Europe, many users are wondering how they can turn it off --> you cant, upsetting quite a few users www.huffingtonpost.co.uk/entry/whatsa... Made in Figma

Europeans are spending way more time online than they did in 2018 — especially in 🇨🇭 Switzerland, 🇬🇧 UK, and 🇱🇹 Lithuania, all up by over 30%. #30DayChartChallenge #Day02 Slope 📊

The Wikimedia Foundation, which owns Wikipedia, says its bandwidth costs have gone up 50% since Jan 2024 — a rise they attribute to AI crawlers. AI companies are killing the open web by stealing visitors from the sources of information and making them pay for the privilege

Quarto + #RStats + Observable = ❤️ New blog post from me about: 👁️ What is Observable? ❓ Why should R users care? 📊 How do you use both together to make interactive charts? Link: nrennie.rbind.io/blog/observa... #DataViz #Observable #QuartoPub

Are you ready for the next #30DayChartChallenge? 🚀 April is approaching fast, and we’re gearing up for the 5th edition of our visualization challenge! 📊 New look and creative prompts to spark inspiration, experimentation, learning. We’ll reveal topics very soon, stay tuned! 🎉 Who’s in?

Impressive visual by NYT, showcasing the waiting list for a kidney transplant. It manages to show all at once: the protagonist, individual persons, not just numbers and what a size ratio of 1:3557 means. 👏 #dataviz www.nytimes.com/interactive/...

You want to create a bespoke graph in python? It's probably possible - with a bit of time and perserverance.🤓 Meet a radial tree diagram of Marvel film box office performance. 100% made in python using numpy, #matplotlib and bezier curves. Dont judge the code 😅 github.com/Lisa-Ho/smal... #dataviz

A rare occasion where I found AI actually helpful. Last year, I used #Midjourney to create a #storyboard for a product vision workshop. Midjourney seemed to perform best for character contuinuation (see blog for more inside-numbers.com/how-to-creat...) Curious: How has AI helped you in your job? 👀💡

Thanks @londondatavis.bsky.social for organising a great hands on workshop on 3D maps and data visualisation with Blender! 👏 Really inspiring to learn from Julian and get started on a few projects. 🙏
