here's a preprint of the unhinged paper i wrote with @lane

we stop just short of saying that the unthinking use of frequentist statistics puts your very soul at hazard

The reVISit team will be hosting an open hackathon at TU Graz in Austria, immediately after IEEE VIS from Monday November 10 to Wednesday November 13. Anyone interested in contributing to reVISit is invited to participate!

@hrbrmstr.dev thanks for the ping!

@erickapitanski.bsky.social very cool project (poking around now) -- I'll be in CA in a few weeks to advise student projects, would be happy to swing by if doable

Going to #CHI2025 in Japan? Interested in running user studies?

Sign up for our virtual CHI 2025 course that teaches you how to use reVISit, a new, open-source user study tool reducing the tedium of study design. Come learn through some practical examples.

Tactile charts are an important tool for conveying data to blind and low vision people via embossed paper. However, tactile charts require high levels of time and expertise to design.

Introducing Tactile Vega-Lite, new work at #CHI2025 led by MIT SM student Katie Chen

A new way to make graphs more accessible to blind and low-vision readers

Designed to help blind and low-vision readers understand graphics, the “Tactile Vega-Lite” system from MIT CSAIL converts data into a standard visual graph and a tactile chart. Accessibility standards...

behold the CONNECTED SPLATTERPIE

kneel before my works, ye mighty, and despair

A connected splatterpie: a connected scatterplot where the points are pie charts and the connecting lines are splines.

Shows three time series, all increasing from 2013 to 2024: (1) How awesome are spline smooths (out of 10); (2) How many charts are dual-axis charts (going up to ~ 2.0M); (3) % of line charts with splines (going up to ~ 60%).

1) Cool VIS study, 2) Help our replication effort! ->

Alexander Lex @alex-lex.bsky.social · Mar 19

How can we use black-and-white patterns in visualization? If you have visualization design experience, we’d love your input! We’re running a short study (less than 20 minutes) where you’ll experiment with designing patterns for a chart.
Please participate here revisit.dev/replication-...
Thank you!

Different visualizations - a map, a pie chart, a bar chart, using black and white patterns.

Also curious about what might be driving this. Are folks with less experience diving into more complex tool ecosystems thanks to AI? Kind of what @mjskay.com was getting at... 🤔

Pre-AI, maybe folks learned better norms for asking for help, etc. over time?

Country Noises.

(Saul Steinberg, 1979)
saulsteinbergfoundation.org

A chart of country noises (lawnmower, rain on roof, frog, mosquito and more) presented to look like sound waves whereas they are more like ornamental border patterns - especially like old letterpress and printing pieces. This is probably what was used for them.

"…there’s one nut we have not been able to crack: anchoring bespoke data visualization as a full fledged profession in corporate settings."

Re-reading this article from 2017 (medium.com/visualizing-...), I wonder — where are we at 8 years on?

There be dragons: dataviz in the industry

I started being serious about data visualization around 2005, when the field was still pretty niche and people like Martin Wattenberg, Ben…

Slightly annoying when a paper describing an experiment doesn't include a screenshot of the actual task participants performed.

(I wrote the paper in question 🫠...)

Cool possibilities for interaction studies ->

Alexander Lex @alex-lex.bsky.social · Feb 10

reVISit 2.0 Highlight: reVISit now supports Vega and Vega-Lite stimuli. You have the freedom to plug in Vega JSON configurations inline, or as a file. You can leverage interaction and reVISit's provenance tracking and interaction replay feature as well, with no extra effort. revisit.dev #datavis

This ggplot chart was generated without any theming support, *at all*.

💯 + reminds me of this recent VIS paper "Image or Information" -> arxiv.org/abs/2307.10571

Image or Information? Examining the Nature and Impact of Visualization Perceptual Classification

How do people internalize visualizations: as images or information? In this study, we investigate the nature of internalization for visualizations (i.e., how the mind encodes visualizations in memory)...

🛫 You can pilot and iterate on the experiment instantly from within a notebook environment.

📈 You can even test data collection and prototype your analyses in the same notebook!

ReVISit 2.0 (revisit.dev) reached several exciting milestones recently:

📁 You can now define an entire experiment in a single file— from trial data, stimuli (visualizations and interactions, thanks to Vega-Altair), study blocks/sequences and randomization, questionnaires, etc.

Crowdsourced Think-aloud Studies w/ full interaction provenance+rehydration, auto voice transcription, and correlation between timelines.

That plus a pile of new features and capabilities in the reVISit 2.0 release.

Check it out & let us know what you think!

Alexander Lex @alex-lex.bsky.social · Jan 23

We’re released reVISit 2.0, the latest version of our open user study platform! There are a LOT of awesome new things in this release that will not only make it easier to run your user study for #ieeevis, but give you new analysis capabilities. #datavis

More LLM reflections

I think a useful model is "everything that in-house counsel is not"

In-house counsel doesn't know how to say yes to you; they're entirely made of blood-soaked wisdom.

LLMs are excitable improv comedy partners with more memory than wisdom; they don't know how to say no to you.
