🦧📉 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
A collage of colorful hex logos from popular ggplot2 extension packages. Each hex represents an R package that expands ggplot2’s functionality. The overall layout celebrates the diversity and creativity of the ggplot2 ecosystem — while being able to just show a tiny sample from it.

Happy 18th birthday ggplot2! #rstats
Balloon wall art inspired by the ggplot2 hex sticker. The display features a hexagonal frame made of black balloons, filled with white balloons inside and surrounded by a background of light and dark blue balloons. A line graph with black balloon segments and round coloured nodes runs across the centre, and the word “ggplot2” is spelled out in black balloon letters below the chart.

Working on the latest #ggplot2 [un]charted lesson about “Handling Caveats When Mapping Variables,” I let loose a bit

The sections ended up fun — yes, and maybe a bit silly at times 🤡

Highlight:
a new #aesthetics anthem as a memorable mnemonic 🎶

Out now for members!
www.ggplot2-uncharted.com
A screenshot of the anthem (and the introductory text to understand the context): Again, ask yourself: Am I setting or mapping? Now, repeat with me...     🎶 🎶 Columns inside, constants out —   That's what aes() is all about 🎶 🎶
