I'd replace "experimenters with "Abusers of innocent creatures".

Is France defined as a multipolygon? In that case, could one choose the biggest polygon in it?

Never thought of oversea territories pulling centroids. I can't suggest anything beyond asking why not use the capital or most populated city coordinates.

2D UMAP scatter plot of countries based on five statistical metrics. Each point represents a country-year. 
The x-axis (umap1) loosely corresponds to income level, with high-income countries on the right. 
The y-axis (umap2) loosely corresponds to year, with more recent years toward the bottom. 
Point shape represents binned overall score (0โ€“20, 20โ€“40, 40โ€“60, 60โ€“80, 80โ€“100), 
point fill represents income category (Not classified, Low, Lower middle, Upper middle, High), 
point colour represents year using a black-to-light-green gradient, 
and point size encodes population. 
Clusters indicate countries with similar profiles. 
China (large cyan point) and India (large orange point) are separated, 
with India moving toward the high-income region and China moving upward over time. 
Legends for all four aesthetics are shown below the plot for clarity.

Tried to improve the plot by adding overall_score as shape.

Scatter plot of countries in a 2D UMAP embedding based on five data metrics. 
Each point represents a country-year combination. The x-axis (umap1) roughly aligns with income level, 
with high-income countries on the right. The y-axis (umap2) roughly aligns with time, with more recent years toward the bottom. 
Point shape and fill encode income category, point size encodes population, and point colour represents year in a yellow-to-red gradient. 
Clusters indicate countries with similar metric profiles. China (large cyan point) and India (large orange point) are clearly separated, 
with India moving toward the high-income region and China moving upward over time. Mixed-income clusters from earlier years appear in the upper-left region.

Relative contribution of number of published papers by country (architecture and built environment research field). The relative contribution of China notably increases since 2019.

If you think of something that could be measured from this SH dataset, I'd be happy to try.

Now, that's a good dark list. Silly word count 0, actual knowledge 1. I wonder if a word count could capture such an insight.

It was my first TidyTuesday, so not much experience here either, just learning, and wrote the first words that came to mind. I read you like Sherlock Holmes stories: which ones would you consider the darkest? I'm suppose this little programming exercise doesn't get anywhere close.

The course emphasises critical thinking and data-driven decision-making, promoting ecofeminist solutions to address the climate emergency and improve liveability in built environments.

Students will acquire tools to assess the multi-scale impacts of architecture on the environment and society. They will learn to manage databases, apply statistical methods, and interpret data using open science principles, with methodologies applicable within architecture and urbanism.

It will explore the causes and implications of the climate crisis and the role, both positive and negative, played by architecture.
