I did it! 30 days of the #30DayChartChallenge 🏁 To survive, I used 22 R packages, forced a single color palette on everything, and shamelessly reuse of datasets. check out the full gallery + code here: below. catch me eating lunch in a non-grid format now. ✌️

#30daychartchallenge / day 23 / seasons I find using {geomtextpath} the easiest way to create beautiful grids for circular plots #rstats #dataviz #ggplot2

#30daychartchallenge / day 09 / wealth How many bar charts can you fit in a bar chart? #rstats #ggplot2 #dataviz

Rodrigo Barreiro @rodrigo404.bsky.social · 08/04/2026

#30daychartchallenge / day 08 / circular It would be beautiful if the data had more variation (look what I’ve become, blaming the data lol). Also, it would be cool if I could add a legend with an image.

finally, the first week of #30daychartchallenge this year I think I would not be able to keep making one plot by day, so things may get out of hand :/ note, there used to be this thing called CDs which we used to listen to music (feeling old)

Rodrigo Barreiro @rodrigo404.bsky.social · 04/04/2026

Let’s go to another #30daychartchallenge I’m so rusty i forgot it took so long to adjust legends. This my main focus is to survive until the end of this without make myself (more) crazy.

One of my favorite hobbies is to crochet. And sadly I never found a well designed crochet pattern mobile oriented. Today I’ve finished a template. Maybe I could create an application for it on my vacation. 😮‍💨 #crochet

finally finished the first look of my makeover of the fastQC report. first i got happy for the result, then saw that the final HTML has ~only~ 16Mb. if you want to check it out, here is the link: html-preview.github.io?url=https://... #r4ds #dataviz #bioinformatics #quarto

Today's (yesterday's) #tidytuesday plot comes with a wall of text, yay 🥲 #dataviz #ggplot2 #r4ds

Rodrigo Barreiro @rodrigo404.bsky.social · 01/08/2025

well, i really sidetracked this weeks #tidytuesday, but finally got something i was somewhat happy with. #r4ds #dataviz #ggplot2

3203

Rodrigo Barreiro @rodrigo404.bsky.social · 22/07/2025

for this #tidytuesday I tried my best to do a subway-like-plot without cheating too much on the y-axis. #ggplot #dataviz #r4ds

Rodrigo Barreiro @rodrigo404.bsky.social · 08/07/2025

I can only imagine how "FUN" was to clean this #TidyTuesday dataset. This is my plot for the week. #R4ds #dataviz #ggplot2

Rodrigo Barreiro @rodrigo404.bsky.social · 02/07/2025

I used to think pattern in plots were some old stuff, but it can look really fine. This is my #tidytuesday plot of the week. #r4ds #dataviz #ggplot

Rodrigo Barreiro @rodrigo404.bsky.social · 25/06/2025

another #TidyTuesday, i'm still quite in shock about the measles outbreak in Madagascar in 2019. Also, when to stop adding plots on plots?

Rodrigo Barreiro @rodrigo404.bsky.social · 12/06/2025

maybe i could just call it tidythursday? #tidytuesday #r4ds #dataviz code at: barreiro-r.github.io/tidytuesday/...

Rodrigo Barreiro @rodrigo404.bsky.social · 03/06/2025

i tried to experiment with python (seaborn) for this #TidyTuesday. 1h+ later i had no plot, only tears. In R, 5 minutes later i had this: #dataviz #r4ds #rstats
