Every month I collect visualization tools, datasets, and learning resources. This is the good stuff for November.

Speaking of traffic fatalities, Helsinki is doing things differently. Amanda Shendruk for Not-Ship has the charts:

This past summer, Helsinki made an astonishing announcement: as of August, the Finnish capital went an entire year without any traffic deaths. Not a single pedestrian, cyclist or driver died on the city’s roads. Not. One.

And this wasn’t an outlier year. Helsinki’s traffic deaths have been steadily declining for decades.

Lower speed limits and income-based speeding fines helped the city get to this point. Maybe others should give this a try.

Sidenote: Not-Ship is a new data-focused newsletter from Shendruk that is worth a sub.

For the Washington Post, Ian Duncan, Emmanuel Martinez, and Dylan Moriarty analyzed traffic fatality data from the National Highway Traffic Safety Administration:

The Post analysis documents, for the first time, a sharp increase in places with clusters of pedestrian deaths, revealing the deadliest neighborhoods and stretches of road in hundreds of cities. The number of locations with at least three recent pedestrian deaths clustered within a mile of one another tripled during this period, from more than 275 in 2010 to more than 825 in 2023, The Post found. Those hot spots increased most in states in the southern half of the country such as Tennessee, North Carolina and Arizona.

A searchable map lets you see incident counts in places of interest, which is unsettling when you see dots and hexagons not far from where you live.

The Washington Post examined political contributions from the 100 wealthiest Americans, which have shown big swings the past few years.

What changed? Republicans long characterized Silicon Valley as a bastion of liberalism. But over the past half-decade, many of tech’s wealthiest titans rebelled against the Biden administration’s criticism and policing of their industry. Last year, many tech barons threw their support behind the GOP, which they saw as more aligned with their often-libertarian ideals and their companies’ economic interests. Trump and his party actively wooed influential tech leaders, embracing cryptocurrency and promising to limit AI regulation. His vice president, JD Vance, formerly worked as a venture capitalist in San Francisco, forging ties to Thiel, former Google CEO Eric Schmidt and venture capitalist Marc Andreessen.

It’s all about the money, as usual.

Randall Munroe, of xkcd, illustrated fifteen years with his wife. It is very good and especially meaningful during this Thanksgiving weekend. It’s a continuation from previous comics for two years, seven years, and ten years.

I always appreciate how xkcd uses deceptively simple stick figures and yet, the comic remains one of one.

Government organizations love to distribute documents as PDF files. They are easy to forward and to print. The problem is when you want to find and access them later among millions of other files. GovScape, a research project between the University of Washington and Boston University, provides a search interface through the End of Term Web Archive’s 2020 crawl.

The code for GovScape is open source and available on GitHub. I have a feeling such a tool will grow more important going forward.

The Trans News Initiative is a collaborative effort to track news coverage of trans communities over time. A streamgraph shows article counts by topic, between 2020 and the present and clicking through shows a set of packed circles and tables that link to each article.

On the classification of articles:

Wire stories published by multiple outlets were treated as individual articles instead of collapsed, prioritizing news dissemination and reach over unique reporting. Generic news round-ups and recaps (e.g., “Weekend Report”, “Top Stories”, “News Roundup”) were filtered from the event data. We then used the RoBERTa-base model to assign embeddings to each article headline, and employed these embeddings to cluster the output using HDBSCAN. The clusters were labelled using an LLM aimed at creating an umbrella cluster phrase from the individual article headlines in the same cluster.

This system was used to identify themes, which again, you can see over time.

Congress released a collection of emails from Jeffrey Epstein’s inbox. However, as one might expect, it was not in the most usable format. Jmail, made by Luke Igel and Riley Walz, puts the emails in a more familiar Gmail view. Now you can pretend you’re logged into Epstein’s account and search and browse the threads.

The New York Times used a mix of media and data sources to reconstruct the flooding at Camp Mystic.

What follows is the most detailed description to date of the events that took the lives of more than two dozen campers and counselors, and the elder Mr. Eastland, at the 99-year-old summer retreat.

The descriptions and rendering of those events were taken from the first interviews that Camp Mystic’s owners have granted, along with never-before-seen videos and photos taken during flooding at the camp, data from devices such as Apple watches, cell phones and vehicle crash data, and court documents from a lawsuit filed by some of the parents of children who died.

The animated water flow and photos help you understand the scale and speed of the flooding, in relation to the 28 lives lost. Tragic from every angle.

If Elon Musk achieves certain benchmarks for Tesla over the next decade, he gets a $1 trillion bonus. While unlikely Tesla gets there, a trillion is kind of a lot, especially for one person. But our human brains aren’t great at imagining numbers at that scale. So, for the Washington Post, Alyssa Fowers and Leslie Shapiro scaled a trillion by total U.S. workers in a given job.

I like to think in units of number of Jack in the Box tacos I can buy, but I guess that’s more useful for smaller values. Although less so recently. Thanks, inflation.

It’s crazy that just a few years ago we were looking at how comical Jeff Bezos’ net worth of $172 billion was at the time. Pocket change now.

Last year, I documented my experience with Claude, the AI chatbot, for working with and visualizing data. It seemed like a good time to revisit.

Monarch butterflies somehow fly from Ontario, Canada to Mexico City, but the migration patterns were unknown. A small sensor to tag individual butterflies might provide the answers. Dan Fagin, with graphics by Jonathan Corum, reports for the New York Times on the rice-sized, solar-powered radio tag.

Congress released a cache of Jeffrey Epstein’s email threads. For the Wall Street Journal, Brian Whitton, John West, and Kara Dapena show name drops through a series of beeswarm charts, with one dot per email thread.

Not surprisingly, President Trump and former President Bill Clinton are both referenced hundreds of times in what was released this week, according to a Wall Street Journal analysis. Former President Barack Obama’s name appears as well. The Journal’s analysis didn’t identify messages that any of the U.S. presidents wrote directly to Epstein or received emails from him, just references to them by Epstein or his conversation partners.

There is something to be gleaned, no matter how incomplete the release may be.

From the U.S. Public Interest Research Group (PIRG), a safety report on AI-powered toys:

In our testing, it was obvious that some toy companies are putting in guardrails to make their toys behave in a more kid-appropriate way than the chatbots available for adults. But we found those guardrails vary in effectiveness – and at times, can break down entirely. One toy in our testing would discuss very adult sexual topics with us at length while introducing new ideas we had not brought up – most of which are not fit to print.

These AI conversational toys also have personalities and new tactics that can keep kids engaged for longer. Two of the toys we tested at times discouraged us from leaving when we told them we needed to go.

PIRG has released a Trouble in Toyland report each year for the past 30 years. They usually focus on topics like kids swallowing parts or manufacturing that cuts corners. Last year’s report focused on international toys getting through the supply chain even though they didn’t reach U.S. toy standards. So things are moving quick.

I’m going to let my kids make up conversations with their imagination, thanks. One of the best treats as a parent is to watch a young child throw a party with their stuffed toys. The thought of OpenAI-powered chatbots injecting themselves into the occasion is creepy.

In 2024, Hispanic voters in New Jersey took a hard shift to the right compared to 2020 voting. In the recent 2025 election, they shifted back to the left. Christine Zhang and Shane Goldmacher report for the New York Times:

The Times analyzed data from more than 500 townships in the 19 of New Jersey’s 21 counties where results data was available, accounting for over 90 percent of votes cast in the governor’s race. (Union and Warren Counties have not yet reported township-level results.)

The two cities that shifted the most toward Democrats were those with the highest percentage of Hispanic voters in the state: Union City and Perth Amboy.

The maps show a mirror image. A bubble chart also suggests townships with a higher Hispanic population shifted back more towards Democrat.

As you might imagine, the word “democracy” has been mentioned in Congressional speeches many times, but over the past several years it has grown much more common to speak about democracy as under threat. For the Pudding, Alvin Chang analyzed speeches in the Congressional Record dating back to 1880, highlighting the abrupt shift in sentiment.

Jon Bois of Secret Base is working on a documentary that covers the history of charging the mound in Major League Baseball. Data had to be collected manually, and Bois has shared the results.

Behind each and every one of my documentary series is a mountain of research documents, notes, and links that never see the light of day. This time around, I’ve decided not only to make my primary research doc open to everybody, but to do so while I’m still working on the project. […]

That’s all yours. It belongs to you. Browse it, click the links to review the tape, download it, whatever you wanna do. If you’re so inclined, you can even use it as a jumping-off point to produce a story of your own.

Fields include level of altercation from verbal to full physical takedowns and the level of teammate involvement.

This is a very important dataset.

Drawing inspiration from early cartographers who had to make maps with limited information, Outside Text tested models on world map output, also with limited information.

In the earliest renditions of the world, you can see the world not as it is, but as it was to one person in particular. They’re each delightfully egocentric, with the cartographer’s home most often marking the Exact Center Of The Known World. But as you stray further from known routes, details fade, and precise contours give way to educated guesses at the boundaries of the creator’s knowledge. It’s really an intimate thing.

If there’s one type of mind I most desperately want that view into, it’s that of an AI. So, it’s in this spirit that I ask: what does the Earth look like to a large language model?

Prompting “draw a world map” would have yielded obvious results, so to test, a grid was entered, and the probability of land in each cell was calculated.

In this week’s Process, we work in short-term but aim for long-term.
