Chart of trends in recovered organs from circulatory deaths
The number of organs available for donation has risen massively in the past five years.
It seems to be the result of technological advances in preserving organs after circulatory death.

When D3 was released in February 2011, it transformed how we build data visualizations for the web and ushered in a new age of unbridled creativity in information design, data journalism, and beyond. Today, it remains the backbone of modern, interactive data viz.

Simulated null distribution for data with a sample size of 100, difference in group means of 5, and a p-value of 0.142
Simulated null distribution of a slope of 0.8 and p-value of 0.002
Finally, we have to decide if the p-value meets an evidentiary standard or threshold that would provide us with enough evidence that we aren’t in the null world (or, in more statsy terms, enough evidence to reject the null hypothesis). There are lots of possible thresholds. By convention, most people use a threshold (often shortened to α) of 0.05, or 5%. But that’s not required! You could have a lower standard with an α of 0.1 (10%), or a higher standard with an α of 0.01 (1%). Statistically significant The p-value is < 0.001 and our threshold for α is 0.05 In a world where there is no relationship between x and y, the probability of seeing a slope of at least 0.901 is < 0.1% Since < 0.001 is less than 0.05, we have enough evidence to say that the slope is statistically significant.
Evidentiary standards When thinking about p-values and thresholds, I like to imagine myself as a judge or a member of a jury. Many legal systems around the world have formal evidentiary thresholds or standards of proof. If prosecutors provide evidence that meets a threshold (i.e. goes beyond a reasonable doubt, or shows evidence on a balance of probabilities), the judge or jury can rule guilty. If there’s not enough evidence to clear the standard or threshold, the judge or jury has to rule not guilty. With p-values: If the probability of seeing an effect or difference (or δ) in a null world is less than 5% (or whatever the threshold is), we rule it statistically significant and say that the difference does not fit in that world. We’re pretty confident that it’s not zero. If the p-value is larger than the threshold, we do not have enough evidence to claim that δ doesn’t come from a world of where there’s no difference. We don’t know if it’s not zero. Importantly, if the difference is not significant, that does not mean that there is no difference. It just means that we can’t detect one if there is. If a prosecutor doesn’t provide sufficient evidence to clear a standard or threshold, it does not mean that the defendant didn’t do whatever they’re charged with†—it means that the judge or jury can’t detect guilt.
I just whipped up this little #QuartoPub site last week that demonstrates how I teach p-values/hyp-testing through simulation both with live OJS and with #rstats, and I think it's super neat! It has examples for diff-in-means, diff-in-props, and regression slopes nullworlds.andrewheiss.com #statsky

Big fan of @observablehq.com and since their preview release of Observable Notebooks 2.0 my team at Fora Health have integrated Notebook Kit into our app. Works really well so far. Quick demo ⬇️
screen.studio/share/TqvyfFbU
Observable Notebook Kit and Desktop 1.1 are out. Headline feature: database connectors! 🎉 You can now query DuckDB, SQLite, Postgres, and Snowflake directly from notebooks. And it’s self-hosted. And it saves results automatically for performance and stable analysis. observablehq.com/notebook-kit...

Atlanta is the most surveilled city in the United States.
But because the Atlanta Police Department claims that releasing the locations of these 60,000+ cameras will lead to terrorism, we’ve not been able to map their locations...

A trick for fitting world maps on phones:
Stack two azimuthal equal-area projections, clipped at 90° longitude, each one rotated 180° from the other.
The bottom map covers the top's Antarctica, which reduces the total height and looks nice.

Two smartphones displaying alternative thematic world maps. The left screen shows a split-continent map with countries grouped and resized by region (e.g., Europe, Africa, Asia) using color to indicate data levels (legend: Hoch, Mittel, Tief, Sehr tief). Smaller countries like Rwanda and Panama are clearly labeled and more visible due to the rearranged layout. The right screen displays a bubble map, where countries are represented by circles scaled to population size and shaded by data intensity. Larger countries like China and the U.S. have prominent bubbles, while smaller countries remain visible. Labels indicate population figures for Switzerland and China.
Better world maps for mobile!
Despite years of mobile-first design, there’s been little experimentation in this area. So we designed our own at NZZ – and validated it in a large user study.

2 by 5 grid of maps showing subsidence rate in 10 American cities, calculated using an average from 2015 to 2021. Houston is dropping most rapidly, with rates over 8 millimeters per year.
Detailed map of land subsidence (red/orange) and rise (green) for Washington, DC. The land is dropping most rapidly in areas of fill (East Potomac Park). Most built-up areas of the sixty are also dropping, but land along the Anacostia River is rising.
A detail to love in these maps by @naemas.bsky.social: the palette is asymmetric (subsiding values go to -8, uplifting values to +2), underscoring how land in many American cities is sinking much faster than it is rising. wapo.st/3F586ov

Ever needed to simplify street networks? I did. And it is a pain. So we wrote an algorithm that does that for us. And can do for you, as it is available as a Python package called `neatnet`.
