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
The landing page of the course "ggplot2 uncharted" with the title teasing it with "Master Data Visualizations with ggplot2".

👾 We've put together a supercut to show exactly what “interactive” means inside #ggplot2 [un]charted 👇

The project became far more ambitious than we first planned, but seeing how rich, detailed, and interactive it has become makes Yan and me genuinely proud of what we’ve built 🚀

We need a total and complete shutdown of WSJ data graphics until our country's representatives can figure out what is going on.

Day 7 of #30DayMapChallenge asked us to think about accessibility. @gsagostini.bsky.social considers two metrics of access simultaneously: distance to a Subway and distance to the subway.

🦧📉 Why are there colorful apes in my #dataviz workshops?

📸 The photo taken years ago by my friend Richard Strozynski has become a tradition in my client projects and courses.

I like to recolor it with different palettes to show how palette design affects perception.

🌏 A compact snapshot on where people live around the globe (2023 data) — over 60% of #humans live in #Asia!

I originally created a more basic version for our new #ggplot2 [un]charted lesson on 🎨 "Color Choice" to discuss color accessibility:
👉 www.ggplot2-uncharted.com/module2/colo...
A treemap showing the world’s population by country, grouped by continent. Each rectangle’s area represents a country’s estimated 2023 population, with labels on the 10% most populous countries. Asia dominates with over 60% of the global population, followed by Africa, the Americas, Europe, and Oceania.

📸 Fun photoshoot yesterday!

Finally updating the profile pic and those “hard at work” photos.

Behind-the-scenes outtake: new office, new favorite mug, new kitten… and me, mid-shrug, wondering how people do this gracefully 😄🤷

I have a slide about an unusual data request I once got: can we show that song choruses are appearing earlier due to the economics of streaming (gotta hook people in early to get paid)? I joked that it's not as if anyone's got a database of song structures. But it turns out that someone has...
An example of unusual data gathering - Compromise! To listen to the weekly Top 40 from the past 20 years would take 96 days and nights Just the No.1 singles would take 17 hours Listening until the first chorus should only take 5 hours So we listened… and got our chart

Did you know, that brown bears can make entire countries happier?

For statistical evidence of that fact, see the animation below

Find the data 🧐🤓
#dataviz #datatoinkratio
One of many line graphs in the NASA Mariner-Venus Report from 1962. Due to the rather black and bold and many grid lines, the straight lines that show the results (which are also black) are almost invisible.

Last week, I crafted my first-ever gauge chart 🏎️ to showcase partial radial plots for our #ggplot2 [un]charted lesson on "coordinate systems"

Thanks to coord_radial(), partial circles like those are super easy now — and of course I couldn’t resist making a polished and animated version 💅📽️ #rstats

ggplot + ggiraph in action ⚡

I teamed up with @cedricscherer.com to put together a fun ggiraph talk for useR conf this year. Of course I had to show an example inspired by him!

Stay tuned for behind the scenes how-tos, tricks, and code. Excited to share more info when the talk is live!

Two redesigns of the cluttered bar chart on Europe’s largest urban areas 📊

Two reworked variants — same data, different goals:
show the data vs. tell a story.

Decluttering, refocusing, adding context, and using visual emphasis can turn a chart into insight.

#dataviz #ggplot2 #rstats #tidyverse
A collage of a decluttered, colorful bar chart and two reworked version — one with ranked vertical bars, all with the same weight, and a cleaner theme direct labels. and a more descriptive title, and the other with a key message highlighting the 7th ranked urban area Berlin in both the title, and the chart itself.

It's always fun to create bad charts for workshops 🤪
#retro #dataviz #workshop #ggplot2 #rstats
A retro-vibe bar chart with many colors and a grey theme with too many labels, grid lines, and font styles, rotated labels, a superfluous legend and more.

Why do we 💙 #ggplot2?

Yes, it's for the Grammar!

But also for the passionate and supportive community — and their steady contributions to the ggplot2 universe: all the extension packages 🧩 that take its impressive flexibility even further, making it more powerful and beautiful 🙌
#rstats #tidyverse
