This week's #TidyTuesday looks at data from a European Citizen Science project examining edible plants. Comparing growth requirements we can find something to grow under a wide range of conditions... just get them out of the shade!

#DataViz #ggplot2
Bar chart showing the number of edible plants which require various combinations of growth conditions. Compares sunlight, water, and nutrient needs for more than 100 edible plant species.

How can you organize NASA's daily astronomy pictures ? Some quick topic modeling of the explanations included in the APOD dataset for #TidyTuesday.
A scatterplot with points representing text embeddings of APOD explanations in 2D space. Topics are indicated by color.

For this #TidyTuesday we look into data on languages spoken across Africa.

I focused on languages spoken in a single country, and make a map indicating which "exclusive" language is spoken by the most people relative to the country's pop.

Code: sethkasowitz.com/posts/2026-0...

#RStatis #DataViz
Map of Africa with country borders drawn. Countries with languages only spoken there are highlighted and labeled. The labeled language is the most spoken of these country-specific langauges. The color of the shading is based on the relative proportion of the country's total population which natively speak the language.

Day 4 of the #30DayMapChallenge and I decided to work out how to plot some arbitrary paths from my Timeline. I spent too much time just working out the exported data structure to look for anything interesting. Just trust that on at least one of these I am driving at an avg of 5 mph for 15 miles.
A screenshot of a city map centered on the Hudson Valley region of southern New York State. Overlapping blue lines trace driving routes.

Immediately falling behind on the #30DayMapChallenge! Playing catch-up today and hopelessly telling myself I will make time to get ahead.

So here are days 2 and 3 using a single data source:

Day 2: Lines
Day 3: Polygons

Real challenge: Calculating arcs 😬

Code: sethkasowitz.com/posts/2025-1...
Map for 30 Day Map Challenge Day 2. Topic is lines and the map is focused on the continental United States. Arcs are drawn from JFK airport in New York to origin and departing airports. The lines' thickness and opacity represent the number of flights along those routes. The 5 most frequently connected airports are labeled: SFO, LAX, MCO, MIA, and FLL Map for day 3 of the 30 day map challenge. The topic is polygons and the map is a choropleth style depiction of the continental United States. States are shaded by the number of flights arriving at the state from JFK airport in December 2024.

Never participated in the #30DayMapChallenge and I've never created a map with Python.

Oake and Willow. Litter mates, menaces, doofuses.
Oake, a fluffy adult cat with a brown/gray/white coat sits atop a bookcase. He is staring down a stuffed lion toy. Willow, a short haired adult cat with a gray and white coat, stands on some furniture. He's looking for a good angle to jump to the photographers shoulder or face.

In the foreground two cats look out a window, seen from the backs of their heads. In the background, a reddish brown squirrel sits on a wooden railing eating something it has just dug up from a potted plant.

Day 1 of the #30DayChartChallenge. Looking at the fraction of the U.S. population with access to fluoride in their drinking water we see this proportion hasn't increased in years.

We were honored to host the 2025 Squirrel Summit. The yard will forever be covered in peanut shells.
Several animals forage around the base of a tree. Grey, black, and red colored squirrels devour peanuts while a mourning dove maintains a safe distance.

One wants to completely supplant my human family. The other tolerates me for my ability to acquire and distribute chicken.
A grey and white cat sits on the corner of a wooden table, looking at nothing. A brown and white longer haired cat sits uncomfortably close to the photographer, staring longingly.

Oake and Willow. Littermates, rescues, life disrupters.
An adult half Maine coon house cat relaxes on a baby's changing table. The room is warm and quiet, and Oake is content in the knowledge that he is preventing me from dressing the reason he gets less attention than he would like. An outrageous short haired house cat perches on the handle bars of a stationary bike. Willow firmly believes that instead of trying to prevent a toddler from accepting terms and conditions on my behalf, I should open the fridge door and leave the kitchen for 2-3 minutes.

This creature is incapable of remorse.
Plants in a pot have been uprooted and soil spread across a carpet, a book, and a laptop computer. A guilty house cat, disturbed by the presence of the photographer, glares after his 3rd nap of the day is disrupted.

One is only perturbed by my presence, the other craves nothing else.

Nature's doofiest hunter.
A cat crouches on a shelf, staring at the photographer. The cat is behind a small gift bag, and is flanked by a baby's chair and armchair. A cat pokes its head through a porthole cutout in a toy tent. The cutout depicts a cartoon seal.
