#TidyTuesday in the style of Chartle showing estimated incidence of TB

Code: github.com/borstell/tid...

#R4DS #DataViz
A line chart in the style of Chartle (a statistics guessing game) on a dark gray background with light gray/white text and lines, showing "Estimated incidence of tuberculosis per 100 000 population". One line is highlighted in coral red, showing the change for Marshall Islands from 2012 to 2023, with a huge surge from around 400/100k to well over 1000/100k in 2018.

Flint water samples #TidyTuesday

Bootstrapped water samples for estimating proportion of samples with dangerous levels of lead

Code: github.com/borstell/tid...

#R4DS #DataViz #ggplot2
A plot with the title "Lead concentration in Flint water samples in 2015", consisting of a distribution plot (left) and a map of Michigan with Flint marked, with a water pipe coming out of Flint ending in a faucet emoji. The subtitle contains a longer text explaining "In 2015, the Michigan Department of Environment (MDEQ) collected 71 water samples in Flint to evaluate the concentration of poisonous lead in the drinking water. The Lead and Copper Rule posits that if more than 10% of samples are above 15 parts per billion (ppb), action is required by officials. The MDEQ originally excluded two samples with high readings, thus resulting in below-threshold readings overall. Suspicious of the results, a citizen science project coordinated by Prof. Marc Edwards and colleagues at Virginia Tech collected 271 new samples, which pointed to generally higher levels of lead concentration than the official MDEQ data had suggested. The plot below shows the distribution of samples in relation to the 10% threshold when each dataset is resampled 10,000 times using bootstrapping (the MDEQ data bootstrapped both with and without the samples originally excluded). When including the originally excluded samples, both datasets would indicate that the Flint drinking water is likely to contain dangerous levels of lead at a rate which would require official action for public safety. In 2014, changes made to the water supply source in Flint, Michigan resulted in a public health crisis with many residents being exposed to dangerous levels of lead in their drinking water.

Friday night early #TidyTuesday of British Literary Prizes.

Wanted it as a bookshelf, made it into a bookshelf 📚

Code: github.com/borstell/tid...

#R4DS #DataViz
A plot with the title "British Literary Prizes (1991-2022): Proportion of women & non-binary authors among literary prize recipients over time". The plot is designed to resemble a bookcase, with each 5-year time period from 1991 to 2022 featured as a single shelf, and books representing individual prize recipients. Women and non-binary winners are color coded pink-ish and light blue-ish, respectively. Women and non-binary authors were in the minority until 2010–2014 and have constituted about half of the winners since then. Data: Post45 Data Collective via TidyTuesday; Packages: {tidyverse, marquee}; Visualization: C. Börstell.

Since I have most of my peer reviews saved, I wanted to see some quick stats on the word length of reviews. I suspected they had gotten shorter over time, but it seems less than I thought.
A scatter plot with the title "Number of words in my peer reviews of original and revised article submissions", with points shown either as red squares (original) or gold circles (revised), spanning from late 2017 to late 2025, with about 4 to 8 data points per year and most points falling between 500 and 3000 words (revised manuscript reviews somewhat lower).

UK weather data #TidyTuesday

Temperature changes over time and some individual temperature extremes highlighted on map
🌡🇬🇧

Code: github.com/borstell/tid...

#DataViz ##ggplot2
A line chart showing temperature changes (daily min and max readings) from 22 weather stations across the UK. The line charts include model fit lines showing average temperatures across stations over time (1970 to 2024), showing the estimated average increase at the right margin (about +1.5 degrees Celsius). On the right of the line chart, there is map of the UK showing the location of each weather station. Four of them are marked with annotations showing the highest (Cambridge, 2008) and lowest (Newton Rigg, 2010) monthly means and the hottest January (Yeovilton, 1990) and coldest July (Lerwick, 1993).

There is something schematic about the two-handed forms for plurals, such that different participants can choose different gestures for the same meaning, but nonetheless involving an iconic plural mapping onto the two hands.
#iconicity
Two gesture sequences in photos of a white man with a dark sweater (head is censored by a black circle). Both show a gesture form produced for the meaning 'combine', with the top image showing the two hands collecting items from multiple sources and moving to a single spot and the bottom image showing the gesturer presenting each hand and then moving them towards each other in front of the torso, finally contacting with intermeshed fingers.

A small sample (n=5) of non-signers were asked produce silent gestures for 100 concepts (50 inherently plural; 50 frequency-matched controls).

They all show a preference for two-handed forms for plural items.
A bar chart showing the distribution of one- vs. two-handed gestures for target (81% two-handed) and control (55% two-handed) items. Next to it, the equivalent bar charts for each participant shows that the pattern is consistent across all of them.

In 2017, I collected a bunch of ratings for a project. The participants were a messy group and the survey tool and design were not ideal, so I always wanted to recollect better data with a better experimental design.

I just did. Seems like the old ratings were pretty solid after all.

Euroleague Basketball #TidyTuesday

A mini dataset, so decided to find a way to plot stadium capacity in an interesting way: went with points along the trajectory of a basketball shot! Swoosh! 🏀

Code: github.com/borstell/tid...

#R4DS #DataViz
A plot that says Euroleague Basketball teams by stadium capacity on a offwhite background and black/gray text. Each data point is plotted as a basketball (emoji) and text label with the name of the team(s) playing at the arena, along a parabola simulating the trajectory of a basketball shot towards a schematic basketball hoop located in the bottom right corner. A caption reads: "There are 20 teams in Euroleague Basketball, playing at 19 unique arenas with a median capacity of 12,700 spectators. The biggest arena by capacity is Belgrade Arena which hosts the teams Crvena zvezda Meridianbet and Partizan and seats up to 18,386 people. The smallest arena is Salle Gaston Médecin which hosts Monaco and has a capacity of 5,000.

Something like this!

Tweaked the calculation to something I had originally intended and included 3-letter endings only.

–arp is very Skåne

I like the distribution of the –red/–röd/–ryd endings, of the same origin

It's super cool!

I used it for a bonus part TidyTuesday two years ago, making a tune out of Taylor Swift song data, saved as an mp3. Spoiler: the tune wasn't/isn't very good!

A graphic in the style of a yellowish page of sheet music. Title says "Taylor's Albums (melodized)". On the right, each album is represented by a line of sheet music. On the left, the text reads: "Each album as a single line of sheet music. The key of each track as a single note. Each note's duration as the relative track duration (z scored) across all albums."

I partially contributed to this week's #TidyTuesday dataset of crane observations at the lake Hornborgasjön, 🇸🇪

I made a minimalist plot of observation maxima – earlier over time – in the style of written notes.

{magick} magic for images!

Code: github.com/borstell/tid...

#R4DS #DataViz #ggplot2
A data visualization in the style of handwritten/-drawn notes on a piece of paper. Title reads "Cranes at Lake Hornborgasjön: Observations of cranes at the Swedish lake peak earlier over time". The graph shows ridgelines along dates from mid-March to end of April (x-axis) across the years 1994 to 2024 (y-axis). The first date each year where that year's maximum number of observations was reached is marked with a little handdrawn X on the year ridgelines. Across all years, there are lines showing the mean and median values for first max observations across years down the middle. X'es are generally farther to the right in early years (i.e. later in the spring) and farther to the left in more recent years (earlier in the spring). In the plot margins, there are embedded images of cranes in flight.

And it's particularly sign languages in the Southern Hemisphere that have been added to the Glottolog database in the past 8 years.
September 23, 2025 at 3:10 PM
cborstell.bsky.social
Because sign language linguistics is a young field, many sign languages were undocumented for a long time, and still are.

In fact, in Glottolog, the "sign language" category is in the top with regard to the increase in number of documented languages across version releases.
A line chart with the title "Cumulative increase of documented languages by "family"/grouping across releases of Glottolog: only showing families with 10 or more languages". It shows the cumulative increase over time with releases of the Glottolog language database. "Sign languages" is highlighted in a turquoise line, steadily increasing, having increased by around 26% from version 3.1 to version 5.2.

#R4DS #DataViz #ggplot2
A plot titled "FIDE chess players by country & birth year: Ranking of the top International Chess Federation (FIDE) countries by the number of rated players (Elo rating ⩾1400) per age group (year of birth). Number of players shown under each flag (percentage of age group in brackets). Numbers under the flags show the number of players (with percentage of totals in brackets)". The plot resembles a chessboard, with a grayish purple background and the rankings being displayed as country flags on top of the chessboard's squares. In the oldest age brackets (left side), European countries are dominating with Germany, Spain and France having the most players. On the right side with the younger age groups, India is quickly rising to the top, in the youngest age group (2010—2021), Sri Lanka is also up-and-coming.

The 🍗 or the 🍳? #TidyTuesday

Looking at the ingredients of over 2000 recipes online, where are different cuisines found on the chicken vs. egg (x-axis) and butter vs. oil (y-axis) scales?

As a Scandinavian, I guess I'm part of the egg+butter outlier!

Code: github.com/borstell/tid...

A scatterplot on a cream white background with the title "The chicken 🐓 or the egg 🥚?". The square grid is split by four reddish arrows pointing outwards north/south/east/west.

Each point and text in the plot indicates where on a scale from chicken (left) to egg (right) and butter (top) to oil (bottom) the cuisine is located. Turkish is found at the very center of the plot, Chinese and Thai in the bottom left (chicken & oil), whereas Austrian/German/Swiss and particularly Scandinavian are in the top right (egg & butter).
