🎄 Hope you’ve got all your presents ready 💝

Google search interest shows a stable pattern:

🎅 “Christmas gift wife” peaks just before Christmas Eve
🎅 “Christmas gift husband” peaks much earlier

#MerryChristmas to all of you! 🎁

📈 Google Trends (Nov 18–Dec 24, 2020–2024)
#dataviz #ggplot2
Line chart of Google search interest for “Christmas gift wife” and “Christmas gift husband” from November 18 to December 24. Bold lines show the average pattern across 2020–2024, while lighter shaded lines represent individual years. Shaded areas highlight which term has higher search interest at each point in time. The chart shows that searches for gifts for wives peak later in December than searches for gifts for husbands.

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 🐱:

🦧📉 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.

#dataviz
A ridgeline chart with two groups over a long period (73 years), with one group being quite constant and one meandering from right to left with multiple hills appearing now and then.

🔦 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

I ignored the strip.clip argument in #ggplot2 for way too long 😲

Combined with a small negative margin tweak, you can place facet labels inside each panel. A tiny trick that makes small multiples feel so much cleaner.

🔵 no manual coordinates
🔵 inherits theme styling
🔵 scales nicely when resizing
Side-by-side comparison of two multi-panel bubble charts faceted by world region. The left column shows the default facet labels placed above each panel (“Africa”, “Americas”, “Asia”, “Europe”, “Oceania”). The right column shows the same charts, but the facet labels are moved inside each panel at the top-left using a negative margin. In the center, there is a title reading “Want to place your facet labels inside each panel?” with an arrow pointing right, followed by a short ggplot2 theme code snippet demonstrating how to move strip text inside the panel.

Designing for a good cause 💝

My daughter’s birthday is this weekend, and she’s setting up “thematic rooms.” Instead of painting and tinkering, she tried her first digital design experience — creating it all in Figma with me 😋😼

#design #birthday #kids
The room sign for "Dunkelparty", a party room with disco light The room sign for "Katzenzoo", a room to groom kittens and play with cats The room sign for "Schminkraum", a room with makeup and face painting The room sign for "Turnzimmer", atraining room for gymnastics (however that looks like, already scared what's gonna happen to our funrnishings...)

👾 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 🚀

🌏 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
