Monotonizing data.
Classical PAV: monotone but step-flattened.
TPM: monotone and trend-faithful, maintaining readable dynamics such as endpoints, mass, slope continuity, inflection timing, and relative growth/decay patterns.

Are you aware of any data visualization designs that use optical illusions to enhance the intended message?

It was an exciting experience meeting so many statistical geeks in one place. Meeting @xangregg.bsky.social in person after more than a decade of social media debates was a particular delight. As he said, we could have talked forever.
Back home after a few busy days in Berlin.
1. Presented at JMP Discovery Summit Europe
2. Met density dots inventor @danz68.bsky.social in person
3. Attended excellent Einstein Award colloquium featuring @elisabethbik.bsky.social @brandonstell.bsky.social @helenajambor.bsky.social

Should we restart the debate about smoothed lines?
The rest of our peers are making progress to cut emissions while Canada is uniquely behind. We need to dispense with this idea emissions reductions are too difficult to do fast & the idea international climate diplomacy is pointless. It's working elsewhere.

Joe Rogan and Donald Trump talking over a connected scatter plot. Didn't expect that. Anyway, triggered by a this thread www.linkedin.com/posts/merod_...
I decided to reinterpret the same data without using the time connected scatterplot designed by Max Roser ourworldindata.org/us-life-expe....

I spent quite a bit of time developing the density dots plot graphics. Originally intended as a replacement for the beeswarms, it soon evolved into a complex graphical encoding technique.
A bridge between the descriptive and inferential aspects of distributions, a quantile and a density estimator.

Looking into the evolution of the relationship between two variables. Using the normalized covariance parts to encode the systematic relationship (how the change of one is reflected in the change of the other). Using different smoothing degrees for interpretation.

this is how a density dots plot design looks using the very same data (yearly cycle perspective).

World Geo Histogram ??
Not exactly a histogram and the geo is only West -- East, but this timeline of civilizations/dynasties has a sort of organic flow. Note how the USSR is handled.

In the best days of Twitter, Xan was sharing exceptionally deep #dataviz takes (I never understood why he didn't amass x10 or x100 followers)
Just look at one of the many cool explorations he shared spontaneously 🤩
