omg - this alt.vis paper about NASA-TLX was styled like the original NASA-TLX paper 😍

Given funding uncertainty, we wrote about why depts & faculty should try to communicate openly with PhD applicants about any changes to their admissions processes, including if it's "nothing has changed".

Let's do what we can (when we can) to prevent cascading anxiety.

LLMs are good at lots of things, but bring some joy into your life and have try to make some simple, image-based tasks.

Listen, everyone's mad that ChatGPT 5 can't capture the full nuance of their discipline. But what about its potential to rapidly develop compelling, engaging visuals for education?

It took me only a single prompt to create this emoji-based multiplication table for my child.
It looks like a multiplication table (with rows and columns 1 through 10), but there are many many errors. For example, the columns go 1, 2, 3, 4, 5, 6, 6, 7, 8, 9, 10, 10, 10. The final 10 only has single emojis as answers. Another example is that there are many cells which don't align with the row/column (33 x 45 or 100 x 80). Each cell also tends to have 1-4 emoji, regardless of the multiplication.

I feel terrible for the students described in this article, because they bought into the lie that they've been hearing from politicians for years - don't study humanities, study computers, and you will get a job. All these students did was listen to what we told them. www.nytimes.com/2025/08/10/t...

I learned about Bill Collins today, CU's 1st black football captain. This image captures Bill at the 1969 Liberty Bowl coin-toss, standing in front of an all-white, never-integrated Alabama team that brought 40 players to stand opposite him.

This wild AI example just happened to me + a colleague trying to decide on "wellbeing" or "well-being" for public material.

Depending on query framing, Google gives inverse recommendations for US audiences!

Almost as if its inferring my preference from order and trying to make me happy 🤔
Left, screen shot of google search results for "well-being vs. wellbeing". Right, screen shot of google search results for "wellbeing vs. well-being" - reversing the hyphenation. When hyphenated "well-being" was first in the query, it said that was the "traditional and preferred spelling in North American English". When non-hyphenated "wellbeing" was first, it said "this was the more common and preferred spelling in many parts of the world, including the United States, Canada, and Australia"

As a fellow "personal & local vis" evangelist, this article is rich with great examples.

Data visualizations are some of the most powerful tools in a climate science communicator’s playbook. However, designing visuals that are clear to the public and policy makers is not a straightforward task, writes @rachitdubey.bsky.social .

So, what works?

Climate change is a slow-moving disaster. We need graphics that capture both its pace and its impact.

ChatGPT is out here gifting my research to other folk today...

> "Studies like “Data is Personal” (Kovacs et al., 2019) show that data framed to reflect local or personal experience increases trust and perceived relevance."

(unfortunately, I'm actually flattered it surfaced in an unrelated query)

The visual design in this article is just straight-up gorgeous.

Congress has passed hundreds of laws protecting federal public lands over the past century through bipartisan efforts and with the support of local governments. Now, Trump’s administration is pushing policies and legislation that upend these protections.

Even if I'm wrong (probably), it's kind of interesting that both publications chose color palettes that forces *every* value into "rising" or "falling" visual schemes. Wouldn't this make every city look a little bit dramatic, even if it was among the most stable?

A wild, not-investigated guess on the vis discrepancy:
Since the two colors (orange/green) diverge around zero, maybe it depends on what "side" you bin the zeroes in your dataset?

If that's the case, I'd probably redesign both to make 0 gray.

Dug up the paper (left) the WPost vis (right) is based on to see how they presented the same data. It's fascinating to me how subtle color differences can shape the spatial patterns we see.

(I can't quite figure out why more of Houston seems to be rising in the paper than the WPost article 🤔)
screenshot from academic paper vis showing sinking areas of Houston. Seems to suggest most of Houston is sinking, but shows more areas rising than WPost vis (next image) screenshot from WPost vis showing sinking areas of Houston. Seems to suggest nearly all of Houston is sinking.

🐟 This is one of the weirder charts in my collection of examples: a set of fish icons to compare funds.

I use it when I talk about visual variables. This chart uses SIZE as a visual variable in 15 different ways, to show 15 different aspects of a fund.

1/4
A stylized infographic features fish illustrations to visually represent different investment profiles. Each fish encodes multiple financial characteristics. The fins on its back indicate the region, distinguishing among the Americas, Asia, the European Union, and Africa & the Middle East, as well as whether the market is emerging or developed. The shape of the tail represents the company's market capitalization—small, medium, or large. The size of the fish's eye reflects its performance, defined as the current return as a percentage of its historical maximum. The contour of the fish's body conveys investment style, such as value, core, or growth. Finally, the shape and position of the fish's mouth and side fin signal the sector classification: cyclical (like materials and financials), sensitive (like energy and technology), or defensive (such as healthcare and utilities). A legend on the right explains the full visual grammar, mapping each fish attribute to its financial meaning.

I think we have overloaded the term "student reviewer", and your response is totally reasonable given that muddiness.
peck.phd
Evan Peck @peck.phd · May 7
I actually don't think that option was intended to capture all students who are also reviewers.

My understanding is it is meant to capture the specific "student reviewer" role that is meant as a training program this year at vis: ieeevis.org/year/2025/in...

More awful news.

The US has been the leader in scientific research for **80** years due to robust funding for NSF, NIH, and other scientific agencies.

All that infrastructure, human capital, and international prestige that we have built over those years is at real risk of just collapsing.

NEW: Starting May 5, NSF will implement an across-the-board 15% indirect cost rate (mirroring policies at DOE, NIH)

Also, NSF staff expect 341 additional terminations today, bringing the total number of terminations to ~1,380.
Effective May 5, 2025, NSF will apply a standard indirect cost rate not to exceed 15% to all
grants and cooperative agreements awarded to IHEs for which indirect costs are allowable.1 The
awardee is authorized to determine the appropriate rate up to this limit.

Crushing to hear of more junior colleagues in the computer science & human-computer interaction (HCI) space whose NSF CAREER grants were terminated this week. I'm hopeful that philanthropic funders can find a way to support this generation of scientists studying online manipulation, bias in AI, etc.

This is one of the worst violations of research ethics I've ever seen. Manipulating people in online communities using deception, without consent, is not "low risk" and, as evidenced by the discourse in this Reddit post, resulted in harm.

Great thread from Sarah, and I have additional thoughts. 🧵

The mods of r/ChangeMyView shared the sub was the subject of a study to test the persuasiveness of LLMs & that they didn't consent. There’s a lot that went wrong, so here’s a 🧵 unpacking it, along with some ideas for how to do research with online communities ethically. tinyurl.com/59tpt988
