Here's the finished version of this #TidyTuesday chart!

📊 Sunburst chart made with #ggplot2 in #RStats
✋ Dropdown interaction added with {ggiraph} with a few little JavaScript helpers
📚 Combined with #QuartoPub

Yes, you can make interactives in R without requiring Shiny!

#DataViz

Thanks so much to those who joined me at the Posit Data Science Lab with Libby Heeren and Nick Rohrbaugh!

Here's what I came up with in ~50 minutes of live-coding a #TidyTuesday chart - a parameterised plot, showing which continents twinned cities are from!

A few more things I want to add: tooltips to show city/country names, dropdown to choose a country, and slightly better text contrast!

This week's #TidyTuesday is all about agricultural tariffs in the USA, and I decided to focus in on tariffs on jam 🍓

Of course, that naturally led to figuring out how to write code to plot jam jars in #RStats!

This week's #TidyTuesday data is all about Global Health Spending 💰️

I created a minimalist world map showing the percentage of health spending on preventive care 📊

Notable upticks in 2021 across many countries, higher % overall in African countries, and lots of missing data

One of my aims for 2026 was to be a little bit less "all or nothing" with projects so I'm pretty proud of my #Genuary2026 contributions!

Still learned lots of new stuff, and had plenty of time left for other things!

Genuary Day 3: Fibonacci forever

Figuring out how to programmatically create Fibonacci tiles

I had a great time talking about the process of creating charts with ggplot2 at @rladiesrome tonight! 📊

Slides and code from the session can be found here: https://nrennie.rbind.io/talks/rladies-rome-ggplot2/

#RStats #DataViz #ggplot2 #RLadies

I'm really excited to be running this session for @rladiesrome next month! 📊

We'll be talking about data viz design, building charts in ggplot2, and tips for how to develop your viz skills!

It's Day 8 of the #30DayChartChallenge, and the prompt is "Histogram" 📊

💻 Another #RStats + Observable combination ❤️
📈 Kept it simple, but figured out more about small multiples (facets), sorting categories, and colour palettes in Observable today!
