Excited to launch "ggplot2 [un]charted" with @yan-holtz.bsky.social! 🎉 An online course to master #ggplot2 with exercises, quizzes, and modules—and hands-on code running in your browser! Still WIP—sign up now for a limited discount: 👉 www.ggplot2-uncharted.com #rstats #DataViz #DataVisualization

Not sure people still read the walls of text these models output when talking to themselves. Caught this one debating whether to stop and ask me first or just go ahead, risking that I'll hate it. And it scares me a little, every time, how human-like their output is designed to be. #Mistral #AI

Excited to share my latest blog on Posit Open Source! During my internship, I built 10 apps and 5 computational biology packages using R, Python, Shiny, and Shinyreact to make scientific research more accessible, especially in rare diseases and cancer. opensource.posit.co/blog/2026-10...

Happy to creatively contribute to this wonderful (yet depressing) screensaver by @karaman.is 👐

I made a macOS screensaver that draws the warming stripes one year at a time. It holds all 1,069 locations from showyourstripes.info and nine ways to build each picture. Free download. Stripes by Ed Hawkins @edhawkins.org karaman.is/blog/2026/10... #ShowYourStripes #dataviz #macOS

The programme just came out, so I created a starter pack with the speakers and organizers of the @visualisingclimate.com conference in Bologna in early November. I found 38 people. Let me know if I got the wrong person or if I overlooked someone.

Friends! Can I ask you a favour? My 🐦 + 📊 course starts next week. I'm super excited but registration is worryingly low. Can you share this with your weirdo nature + art + code friends? jerthorp.me/learning

Heute startet die Fußball #Bundesliga Saison der Männer 2026/’27. Wenn alle Fußballfans den Bundesligisten in ihrer Nähe unterstützen würden, welches Gebiet würde dann welchem Verein "gehören"? #dataviz 📊

Luckily, I don't have to wear glasses! 🫠

I'm puzzled by this paper's lead chart. Connecting socioeconomic status levels emphasizes that difference, which is not the point of the paper. I reordered the data to connect across time points which helps see the gap widening over time and a different trend shape for the P and HP schools. #dataviz

This week we released the #maps module in #ggplot2 uncharted — and we cover a loooooot of maps in the 4 lessons and 19 exercises! ... and this collection doesn't even feature each 👀 As usual, the first lesson is available for everyone 🤙 www.ggplot2-uncharted.com/module5/spat... #rstats #tidyverse

We had 165+ people joining our #dataviz session on "Guide the View" 📈 from all around the world on Monday 🎉 Thanks for all the enthusiasm and engaging participation 👐 If you missed it or want to revisit an example, I’ve uploaded the slides here: 🔗 cedricscherer.com/slides/Scher...

One more for the cheese lovers. 🧀 German cheese exports and imports from and to Austria between 2001 and 2025 in the style of William Playfair. #30DayChartChallenge | Day 21 - Historical #dataviz

Next week I'll give a talk on how to "Guide the View" in DataViz (likely with a bit of love coding in our "#ggplot2 uncharted" setup 🤩) Save your spot and sign up here 👉 luma.com/z5ea6oew #datavisualization #rstats #learning

New lesson live 🚀 Before starting to talk about #maps with #ggplot2, we cover "Spatial Data". 🧱 What are the building blocks? 🌉 What is the SF revolution? 🍊 How to peel an orange? (Wait, what?!) Curious to learn more? This lesson is freely available 👐 www.ggplot2-uncharted.com/module5/spat...

Late for #Day8 of the #30DayChartChallenge, but the "Circular" prompt is the perfect excuse to share yet another #ggplot2 trick! 👀 Tried the "new" #coord_radial yet? Compared to coord_polar, it: 🌀 bends grid lines 🌀 places labels naturally 🌀 allows inner radii 🌀 handles partial circles easily

To create great visuals, you need to combine #code syntax with #dataviz best practices 💻🤝🧠 In "ggplot2 uncharted," you'll master both! One powerful insight: Knowing when to stop adding more to your chart—and start using #facets or #compositions. Give it room to breathe! www.ggplot2-uncharted.com

#Day8: Circular A decade of bad air. Air quality in India’s major cities has stayed consistently poor, often reaching hazardous levels, with no signs of improvement year after year. #30DayChartChallenge #dataviz #airpollution #cleanair

Day 2 of the #30DayChartChallenge: Pictogram! A quick count of animals in the yard over a short span yesterday morning. I love marmots and this does not do them justice. Watercolor & ink.

For today's #30DayChartChallenge #Day1 "Part-to-Whole", I'm not sharing a polished #dataviz but a lesser-known #ggplot2 trick 🧙‍♀️ Turn your area chart into a timeline of relative shares by changing the position argument to "fill" 🤙 Example from our "gpgplot2 uncharted" course: ggplot2-uncharted.com

Just one day - or, depending on your timezone maybe just a few hours - until the next #30DayChartChallenge kicks off. 🚀 1 prompt for each day of April across 5 categories to spark inspiration, experimentation, and learning. 📊 Who's in? 👀 #dataviz #datavisualization

I've been working on overhauling my site (again). This was also a perfect opp to show an old project some love for #30DayChartChallenge. Day 1 Part-to-Whole. Breakdown of The Global Human Day. It's an exploratory piece for curious folks who like to play with data! indievisual.tech/projects/viz...

Join us in Bologna, Italy, 4–6 Nov 2026 for Visualising Climate — the first global conference fully dedicated to climate data visualization and its power to transform public understanding of a changing planet. Come see the data. visualisingclimate.org #VisualisingClimate2026 #DataVis #ClimateCrisis

I just opted out of a workshop with a heavy heart when I learned it's a collab with DataCamp. No matter what, I'll maintain my boycott — why? Here is a detailed overview: dnlmc.medium.com/dont-use-dat... There are soooo many other options that value you, the community, and the instructors!

This so much fun!

"Vibe Coding" the old-school way 🌈 I was prepping a ggplot2 lesson when a stat_summary() error went sideways. Instead of fixing it, I leaned in. Sometimes the best dataviz is found in the detours. (Or at least, the most joy on a Monday ☕️) #rstats #ggplot2 #dataviz #TheSimpsons

New Year, New Colour Tool for you data visualizers and maybe the odd designer obumbratta.com/colour

How likely is ‘likely’? Does ‘likely’ have a higher probability than ‘probable’? I put together a quick quiz so you can see how you interpret probability phrases, then see how you compare with others: probability.kucharski.io

I wrote a lil post on the amazing work that @ginareynolds.bsky.social does championing ggplot2 extension developers and teaching others to build their own! The post features the Scrollytelling Quarto extension and the group's cute #RStats hex 🐱: rworks.dev/posts/ggplot...

Mesmerizing data patterns. #dataviz

🔦 new `focus` argument added to {hexsession}. Specify packages to highlight by dimming all the others. also suggested by @emilhvitfeldt.bsky.social and inspired by @kellybodwin.com's hex shirt with dimmed logos. example below uses dark mode hexsession.liomys.mx
