Dear interwebs. We're trying to find out how many scientific papers use a specific visual, e.g. upset or circos. Any ideas on how to identify these? A search for the term doesn't work because it is not always named/referenced.

In preparation for a #dataviz course at the @emblebi later this month, I've created a cheatsheet for creating custom SVG images in #marimo #python. If anyone finds errors: let me know! aida-lab.be/assets/marimo_sv…

Being dependent on US services has become a clear liability: head prosecutor of International Criminal Court has lost access to his email (apnews.com/article/icc-trump…). Can #kuleuven move towards open source/EU software? cc @SeverineVermei1 @TBaelmans #ict

FFS X... Not able to edit a post without paying? Here's the complete message. Our latest paper is out: peerj.com/articles/cs-2792/. We added functionality to the #HDBSCAN clustering algorithm to also detect branches hdbscan.readthedocs.io/en/la… #eda #datavis #clustering

FLASC: a flare-sensitive clustering algorithm

Exploratory data analysis workflows often use clustering algorithms to find groups of similar data points. The shape of these clusters can provide meaningful information about the data. For example,...

Are you a biologist interested in data visualisation to help you explore complex data or create effective visuals? If so, make sure to register for the course that we're organising at the EBI in June ebi.ac.uk/training/events/da… #biovis #viz #dataviz

For what it's worth: moved to Bluesky. Since quite a long time already the feed I get on twitter/X was not useful for me at all. On Bluesky I get to interact with people again... Find me here: bsky.app/profile/janaerts.bs… if you're interested in #dataviz, #omics, #bioinformatics

It happened. I messed up my #python installation on my #mac... Now trying to find out the best/safest approach to get it all working again.

Datamapplot 0.4 is out now, and has far more powerful and effective interactive plots. Here is an example of a Data Map of 2.4 million papers on ArXiv, ready to be explored.

Do you want to test dimensionality reduction algorithms with your data? I made an interactive @observablehq notebook were you can try FastMap, UMAP, TSNE and more via Rene Cutura's #druidJS in a web worker (thnks @recifs) #dataviz #ML 👉🏼observablehq.com/@john-guerr…👈🏼

I have seen all 4 of these lines of best fit in published peer-reviewed papers and oddly the top left is probably the rarest type 📉

Most common 4-digit PIN numbers - from an analysis of 3.4m leaked from several #databreaches by the late great @DataGenetics informationisbeautiful.net/v…
A heatmap reveals the most common 4 digit PIN numbers, visualised from the data leaked from several large data breaches. The horizontal axis plots the frequency of the first two digits, the vertical axis the second two digits. Clear (and somewhat predictable) patterns emerge from the dataset. A diagonal line of ‘heat’ from bottom left to top right reveals people choosing double digits (2323, 6868 etc). A strong horizontal line at the 19 point shows people using their birth year as a PIN code (1971, 1998 etc). And a large amount of heat in the bottom left shows how people commonly use their birthdate in a MM/DD or DD/MM format. The most common code in the set is 1234.
