I've written a short blog post introducing "The Art of Visualization with ggplot2"!

This book is all about the end-to-end process of creating charts with #ggplot2 📊 including data wrangling, sketching, and styling your plots!

🚨 New #DataViz post!

I explore smart alternatives to a broken chart and highlight why avoiding bad practices matters.

👉 Which alternative do you prefer? Let us know in the comments!

Insightful post by @darraghmurray.bsky.social about the public backlash when the Australian Bureau of Meteorology changed the color palette for rain radar data:

Colour as Strategy and Aesthetics: What the Bureau of Meteorology’s Radar Teaches About Data Visualisation
An ill-fated radar redesign reminds us that colour decisions are never cosmetic, they define how data is read and believed.

The worst charts I've ever seen at work
A 3d bar chart for one single data point ("yes") showing 10 people would "cook this recipe at home" A 3d line chart that is almost impossible to read showing (I think) numbers of people who would use coconut oil, olive oil, or vegetable oil when eating starchy foods? A totally illegible bat chart (2d this time, phew) showing numbers of people leaving different free text comments to a survey. The axis includes half person points on the scale. 2 people appear to have left the same illegible comment. Why does this exist?

I just need 1 more dataset for #TidyTuesday 2025! Thank you so much to those of you who have submitted datasets!

The submissions have allowed me to make progress on a long-planned huge maintainability and usability improvement for TT, coming in 2026!

• %notin% table newly in base is an idiom for ! (x %in% table) and provided almost entirely for convenience and code readability, from an R-devel suggestion, after many years of private definitions mostly hidden in packages, including in R's tools package.

We're looking at cars in Qatar for #TidyTuesday this week - "an international and modern version of the now-ancient `mtcars`" data! 📊

➡️ 9 ways to visualise the distribution of a variable

Thanks to @andrew.heiss.phd for curating this week's dataset!

How do large language models interpret words relating to probability like “unlikely,” “probably,” or “almost certain"?

The below shows what happens when we compare judgements from different models to a benchmark dataset of human judgments (data from: github.com/zonination/p...).

One of the things I talked about in last week's #DataViz workshop is that sometimes you have an idea for a chart and sketch it out, but you don't know whether it will actually work until you try it with the real data. 🧵1/5

HEY! YOU! ggdibbler 0.6.1 is finally up on CRAN!

You can now pass random variables to any aesthetic in any ggplot geom/stat. If you can express it as a distribution, ggdibbler can plot it. It also works with ggplot extensions, like gganimate. #rstats

Spotify has laid off thousands in recent years, while reportedly paying artists $0.003 per stream.

Spotify profits rose 28% in Q3. Its CEO is worth $9.8 billion. It's making money off ICE recruitment ads.

Don't you think it's time put a wrap on corporate greed and exploitation?
