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!

t's the Prism palette from Carto (via the rcartocolor package). Not the best palette for encoding groups with the same visual weight but I was reminded of a rainbow by the chart and it just felt right, vibe-wise 😁

"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
A colorful data visualization of IMDb ratings for the first 11 seasons of The Simpsons. The chart uses a "small multiples" layout where each season (S1—S11) is represented by a vertical column. Individual episode ratings are shown as small white circles plotted against a vertical axis ranging from 5 to 9. Each column features a unique, vibrant color—starting with purple for S1 and moving through blue, teal, green, yellow, orange, red, and ending in grey for S11. A horizontal line in each column indicates the season average, while a unique "stepped" gradient effect creates horizontal bands of color that grow lighter toward the top, highlighting the density of the episode ratings.

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

🎄 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 🐱:

I was mostly joking as there's history of "unknown features" that Thomas killed 😁 Negative margins are a great hack, not only in R so I'd def be open to create an PR if that's helpful!

Yeah, I couldn't think of a reason, too, but you also removed the ability to pass into ggsave() - what a bummer back 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

Please don't remove it though! Negative margins are one of the key "concepts" together with empty lines to hack the layout 😊

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 🚀
