Sharing the current stage of an interactive violin visualization project. The concept is already there, even if the implementation is not yet as clean as I’d like. iOS rendering quirks forced heavier drawing logic than expected. danz68.github.io/visualprojec...

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.

Should we restart the debate about smoothed lines?

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.

Triggered by Carlos Barboza LinkedIn post, www.linkedin.com/feed/update/... 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. From: www.pinterest.ca/pin/14080623...

I'm happy to welcome you at bsky @xangregg.bsky.social 🙌 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 🤩 x.com/xangregg/sta...
