And it's finally here!

Day 29 of #30DayChartChallenge - black'n'white

I used to love watching Laurel & Hardy films when I was a kid so it was pretty easy to find a dataset for the penultimate day's theme. Here's a look at the ratings for the duo's short vs movies.

2/2 post for day 20 of #30DayChartChallenge. Looking at US military aid & "smart" weapons supply during the same time period as the attacks and casualties in 1/2.

Stopping at that and hoping to do better for another prompt.

#30DayChartChallenge – Day 8, Diverging

Qatar's population is heavily skewed toward working-age men, a reflection of its reliance on a massive male migrant workforce. This is how labour demand, not natural population growth, drives much of the country’s demographics.

52% der Gemeinden sind somit recht klein (<2000EW). Mit Linz als 3. größte & Wels als 8. Stadt Österreichs und heterogenen Markt- & Stadtgemeinden dazwischen ist klar, dass Lösungen für die vielfältigen Herausforderungen in Regionen gedacht werden müssen

Spent way too long thinking of the creative for this but it was fun showing how big the number of plastic bottles are compared to glass.
Writing custom force clusters and collisions in d3 force was spicy 🌶️

Day seventeen of the #30DayChartChallenge 2025

Topic: Relationships / Birds

Horizon charts are great for showing multiple time series in a limited amount of space. Sometimes, you really don’t have much room but still want to show the density or intensity of events over time.

Day 4 of #30DayChartChallenge: Big or Small 📊

Just 162k of the world’s largest farms (>1000 ha) control 38.6% of agricultural land. Meanwhile, 374M small farms (<1 ha) manage only 6.7% 🫣

I visualized this imbalance using a radial chart - form meets function 😅

They turned two and realized that their age doubled in the past year. The kid is right to be concerned.

An inverse of this is why time flies as we get older. Each additional moment is a smaller and smaller fraction of our total experienced moments.
