Thanks to code-first, open-source tools, LLMs are REALLY good at making Shiny apps. But, how good are they at making **good** Shiny apps? 🤔 This is the sort of question that Shiny QA Engineer Karan Gathani is thinking about. And he'd like to discuss it with you tomorrow at the Data Science Lab!

We're thrilled to be joined by @shikokuchuo.net tomorrow on the DS Lab to learn about asynchronous programming (and parallel programming, which it turns out is different!). Charlie is the author of mirai, which enables them in #RStats tools like Shiny and purrr ✨ See you there! pos.it/dslab

Practicing my #Python with plotnine for the #30DayChartChallenge: Day 6: Reporters Without Borders World Press Freedom Rankings for G20 Countries

A heatmap showing RSF World Press Freedom Index rankings for 19 G20 countries from 2014
to 2025. Each cell displays the country's rank for that year, colored on a blue-to-red
gradient where blue indicates a low rank (more press freedom) and red indicates a high rank
(less press freedom). Countries are ordered from best average rank at the top to worst at
the bottom. Germany, Canada, Australia, the United Kingdom, and France consistently appear
in the top 10–45 range and show predominantly blue tiles throughout. The United States and
Italy occupy the middle of the chart with purple tones, showing moderate rankings in the
40–80 range. Brazil, Indonesia, Mexico, India, Russia, Turkey, Saudi Arabia, and China form
the bottom tier with deep red tiles, reflecting persistently high ranks above 100–170.
Argentina shows notable improvement between 2021 and 2022, dropping from rank 68 to 29.
China and Saudi Arabia remain among the lowest-ranked countries across all years.

For #30DayChartChallenge Day 3: Mosaic, I used Posit AI in RStudio to update an #RStats plot that I created back in 2018. It's been a while, so it was very helpful to have something to work with and help troubleshoot. I recorded the session if you want to see how it went! youtu.be/pD0JU2hu5bI

Stacked bar chart of percentage distribution of enrollment in public elementary and secondary schools by race/ethnicity and state in 2022. It shows significant variation in student demographics across the U.S., with White students making up 51%.

Did you know you (yes, YOU!) can contribute to base R? Base R is the foundation of everything #RStats. If you’ve ever found a bug or thought of an improvement, you can help shape the language. Join @ellakaye.co.uk on the Posit Data Science Lab tomorrow to learn how to get started! pos.it/dslab

Have you ever seen anybody have so much fun using Git? 😄 On the Data Science Lab, @libbyheeren.bsky.social & I collaborated using Git & GitHub in Positron. It has great features for branches, PRs, & best of all: fixing merge conflicts 😰 Check the episode out (hehe): www.youtube.com/watch?v=JTv4...
