Excellent essay from Giorgia Lupi on the steps of craft -- and how AI *can* be used to support it. AI can be a powerful tool to accelerate some kinds of work -- but only with careful attention to what we lose each step of the way.

I combined my love of #datavis with a different passion -- the rich text of the Hebrew Bible, or Tanakh. The Torahmap places every verse of the Tanakh in a fixed spatial position, then plots overlays over it. You can play with it at torahmap.org

Don't we all sometimes wish our lives could be summarized as "loved to scuba dive and take acid." (I recognize her accomplishments were actually quite substantial, both in acting and in diving technology.) www.nytimes.com/2026/08/16/a...

A diving feat landed her on the cover of Sports Illustrated and led to a film and TV career. She also took part in one of the first LSD studies.

- Folkloristics - Story structure - microeconomics - statistics - social media technologies as information systems (in 2000!) Fascinating exercise to look back at those!

Proving that Poes Law predates the internet, I genuinely have no idea whether this letter is a ribbing or tongue in cheek pride.

I want to talk a little more about discoverability. I often find that the creators of AI-driven services have a very specific set of scenarios in their minds -- but then advertise extremely broadly. Unlike a button on a UI, there's no way to know what the creators have in mind!

I'm interested in Anthropic's Qualitative AI study, with lots of questions about both what they learn and how to use the results. www.anthropic.com/features/81k... But from a visualization point of view, there's something I noticed that's bothering me. Those dots are impressive.
A map of the united states, purporting to show locations of survey respondents. The outlines of the states of Washington, California, and Florida are densely filled.The caption: "Each dot represents 4 respondents"

Um … we don’t have children practice handwriting because there’s a shortage of the letter ‘a’ in the world. We don’t have them learn times tables because the economy needs a piece of notebook paper that says “4x3=12.”

I’m less enchanted with the question “what does a lefty with the power of Trump” look like, because the best possible outcome is a world where every few years we lurch between lefty utopia and corrupt dictatorship.

more and more frequently, trump makes comments that make it seem like he is vaguely aware of the fact that his entire inner circle and cabinet are all scheming viziers, he's just sort of indifferent about it
Trump referenced a weekend conversation with Oregon Gov. Tina Kotek, and he alluded to being told by Kotek that the reality in Portland is different from what's being portrayed to him.

"I spoke to the governor, she was very nice," Trump said. "But I said, 'Well wait a minute, am I watching things on television that are different from what's happening? My people tell me different.' They are literally attacking and there are fires all over the place...it looks like terrible."

I carried out the same exercise in metric, too: the number of hours during which the temperature (in C) is the latitude. Cooler equatorial oceans -- and a long span of northern Africa and south America. danyelf.github.io/degree-degree/
A screenshot from the Degree-degree visualization. The interface allows the user to pick between different temperature modes; the main visualization shows a globe, with colorful bands running through central South America and northern Africa and across the oceans

A friend posted a photo, sunbathing from Scandanavia a little bit ago, captioned "60 degrees at 60 degrees!" That made me wonder how often that really happens -- where on earth is the temperature the same as the latitude, and how often? I answered that at danyel.github.io/degree-degree
A screenshot of a visualization showing a globe; a purple streak runs across the northern Atlantic ocean and diffuses into a darker purple across Asia.  A control panel on the left would allow the user to explore the map further.

The other day, I watched a (small local) LLM melt itself down. I was testing out Ollama with the 8b Deepseek model. I gave it a moderately-challenging technical question -- how to make a Javascript and Python package talk to each other -- and hit "go". Three hours later...
An Ollama UI: 
"I’m interested in using Python to drive Deck.gl. Do you know anything about that?"

This is hilarious - ChatGPT hallucinates repeatedly about a nonexistent feature on another website (confusing people), eventually leading the site's owners to implement the feature. www.holovaty.com/writing/chat...

Given that these grotesque abuses are being conducted for our supposed benefit, what do you imagine they'll do when Jews are not sufficiently grateful? What will be the punishment? And which Jews and Jewish orgs will cooperate? May God give us soft hearts and strong spines.

If something reduces death by 30%, then removing that thing increases death by 50%. There are about 40,000 deaths by flu annually, placing it just behind liver disease and self-harm as a leading cause of death. With no vaccine, I bet we could make it up to 60k and hop 3 steps in the rankings!

I suspect that the person at OpenAI who saves 5% on a power cost gets a much smaller promotion than the person who shows how to get a 5% increase on a loss function. Cost isn’t the issue, so cost isn’t an issue.

I seem to have two different blog entries -- or, perhaps, rants -- half-written. Help pull me off the fence before I go away for vacation! Which would you rather see? Option 1: Visualization Is About Comparison (and anyone who disagrees is trying to sell you a gauge)

Finally got a chance to read these comments on box plots. I think it’s really important to realize that the visualization forms of the mid 20th century were doing really different work than 2”we do today.

For #30DayChartChallenge - day 26 - ai I wanted to make a chart that showed generative AI generates expected seeming results consistent with the kind of corpus associated with the prompt, with no understanding of truth, facts, logic, or causality. So I had chatGPT supply the data for the graph.
Do not go to Generative AI for any outcome that expects truth.

It’s surreal. Vaccination is one of the easiest-to-quantify, mind-boggling successful health discoveries ever. A solid “w” ticked on the human column.

It's time for the IEEE Vis conference. I'm not in Oz this year, but the paper listing is online ieeevis.org/year/2023/in.... Authors are pretty good about putting their papers on arxiv ; I've been downloading and following along.

I got to use this data-first philosophy was my work at Honeycomb on BubbleUp. We figured out the visualization first, and the way it would fit into the interface much later. danyelfisher.info/blog/2023/7/...

When I first learned about interface prototyping, we distinguished between high- and low-fidelity prototypes: cardboard and wireframes vs elegant, near-functional images. I've been chewing on how (I think) data visualization breaks that model. danyelfisher.info/blog/2023/7/...
