This week's #TidyTuesday is about twin cities. I built a scrollytelling map about Rio de Janeiro's 93 sister city agreements Made with Quarto and Closeread Interactive: 019e2679-54db-2e9a-2e03-8bbc8b92210f.share.connect.posit.cloud Code: github.com/gkaramanis/t... #RStats #dataviz

This week's #TidyTuesday is about Italian industrial production. A simple line chart combining Istat statistics with data from Wikipedia Code: github.com/gkaramanis/t... #RStats #dataviz

This week's #TidyTuesday is about US agricultural import tariffs. Sugar is the only category with a hard annual import quota. Once that fills, trade effectively stops. Code: github.com/gkaramanis/t... #RStats #dataviz

And that's a wrap for #30DayChartChallenge! The personal theme for this year was Uppsala transportation. Additional constraints were using the same color palette, fonts, plot orientation and dimensions across all plots. #Rstats code for all 24 plots at github.com/gkaramanis/3... #dataviz

This week's #TidyTuesday dataset comes from the at-sea seabird records held by Te Papa Tongarewa, built largely from the handwritten logbooks of Captain J. Jenkins, who recorded 6583 bird sightings on Southern Ocean voyages from 1969 to 1988. Code: github.com/gkaramanis/t... #RStats #dataviz

This week's #TidyTuesday dataset comes from RepairMonitor, which has been logging repairs at volunteer-run Repair Cafés worldwide since 2015. Are older things harder to fix? Depends on the category. Code: github.com/gkaramanis/t... #RStats #dataviz

This week's #TidyTuesday dataset is seven years of daily ocean temperature measurements from Nova Scotia's coastline, recorded at depths down to 40 metres by the Centre for Marine Applied Research Code: github.com/gkaramanis/t... #RStats #dataviz

This week's #TidyTuesday dataset is a million digits of π, which is far more than anyone will ever use. The plot shows how many digits we actually need. Spoiler: science caps out way before the computers do Code: github.com/gkaramanis/t... #RStats #dataviz

Another week, another Sims 4 CC update! A laptop with blurry #Rstats hex stickers and @kjhealy.co's #dataviz book (first edition!) with a broken texture, both works in progress. Textures are hard 😅

It's been some time since I shared a making of video! Here is one for last week's #TidyTuesday

This week's #TidyTuesday maps Norwegian salmon farming mortality rates across 11 coastal production areas. Circle size shows mean monthly mortality rate. Color and labels show the change between 2020–22 and 2023–25. Code: github.com/gkaramanis/t... #RStats #dataviz

Sims 4 CC update! Two #dataviz posters and a #Rstats onesie based on @allisonhorst.bsky.social and @dgkeyes.com’s future R superstar aardvark! 😍 allisonhorst.com/everything-e...

This week's #TidyTuesday looks at how people interpret "highly likely" and "highly unlikely", based on the CAPphrase survey by @adamkucharczyk.bsky.social. Non-fluent speakers tend to take the words at face value (though much smaller sample) Code: github.com/gkaramanis/t... #RStats #dataviz

Going very minimal for this week's #TidyTuesday looking at judged likelihood of likelihood-expressing phrases in English. Code: github.com/borstell/tid... #R4DS #ggplot2 #DataViz

Started playing Sims 4 a couple weeks ago. Surprised there’s no #rstats or #dataviz CC out there, so I’m on it!

This week's #TidyTuesday is about Hermann's tortoises in North Macedonia, where males now vastly outnumber females and the population is collapsing toward extinction. Connected scatterplots are hard to read but I like to try them from time to time Code: github.com/gkaramanis/t... #RStats #dataviz

This week's #TidyTuesday is about Science Foundation Ireland grants. Used {tidytext} to find the most distinctive words in proposal titles, then fitted them inside the bars with {ggfittext}. You won't believe 2020's most distinctive words Code: github.com/gkaramanis/t... #RStats #dataviz

New Zealand once had over 20 sheep per person. Animated this week's #TidyTuesday data showing how sheep numbers, human population, and their ratio have changed from 1960 to 2024. The flock has been shrinking while the population keeps growing! Code: github.com/gkaramanis/t... #RStats #dataviz

Mapped all the 2026 Winter Olympics venues across Italy for this week's #TidyTuesday. Started simple but kept adding stuff because I couldn't stop myself, had way too much fun working through it all! Code: github.com/gkaramanis/t... #RStats #dataviz #olympics

This week’s #TidyTuesday was about edible plants. Not sure if this plot makes much sense, but I had fun experimenting with bitmap fonts and color gradients for the plant names and temperature ranges. Code: github.com/gkaramanis/t... #RStats #dataviz

For last week's #TidyTuesday, I made a plot about the composition of micro-enterprises, small businesses, and larger companies across different owner types in the Brazilian business registry. Code: github.com/gkaramanis/t... #RStats #dataviz

What words define NASA's Astronomy Picture of the Day? For this week's #TidyTuesday, I analyzed decades of APOD descriptions to find the 50 most common concepts and their connections. Code: github.com/gkaramanis/t... #RStats #dataviz

Having some fun recreating images in ggplot with the help of magick. This was made with geom_ribbon and stitched together with magick::image_animate. #Rstats #dataviz

Africa has over 2 000 languages. For this week's #TidyTuesday, I tried to visualize this extraordinary diversity with a treemap and a geofaceted map Code: github.com/gkaramanis/t... #RStats #dataviz

For this week's #TidyTuesday, I visualized James Bond's drinking habits across the 12 novels using a waffle chart, based on the 2013 study "Were James Bond's drinks shaken because of alcohol induced tremor?" Code: github.com/gkaramanis/t... #RStats #dataviz
