For NBC News, Joe Murphy shows the play rate on Last.fm for Mariah Carey’s “All I Want for Christmas Is You” as a set of calendar heatmaps, since 2006.

The song was released in October 1994. The data doesn’t go back that far, but I’d wager it played mostly in December, and then plays kept shifting earlier until leaking in to August. I’m looking forward to a couple decades from now when I can remind the young folks that this wasn’t always an Easter song.

Word clouds show key terms or phrases that appear in a body of text. Everyone loves them. Martin Wattenberg turned it around to show the words that do not appear, with words sized by how often they appear in other text. This is the anti-tag cloud for Winnie the Pooh:

Fun. I wonder if the same logic can apply to other types of missing data.

Some jobs require a lot of standing, crouching, and climbing, whereas other jobs require little movement and you sit all day, turning into a sloth-like creature that gets up sometimes to eat and go to the toilet. I’m not projecting, you are.

For the Pudding, Alvin Chang visualized the spectrum of sitting and standing jobs. The interactive version lets you zoom in to pixel art characters working their jobs within force-directed capsules. While the interactive is fun and good for exploration, the video version provides a more narrative tone with Chang narrating:

I think I like the video version better for the clear direction. I’m a nerd and get distracted by the interaction too easily.

Check out the data yourself. It’s from the Occupational Requirements Survey by the Bureau of Labor Statistics.

Liuhuaying Yang aims to clarify the names and sounds that get lost when translating language that relies on tones to spellings that do not capture the differences:

This project explores the complexity of Chinese names and the challenges of using Pinyin romanization, focusing on how it impacts the distinction between surnames and given names. While Pinyin simplifies Chinese characters for global audiences, it can create ambiguity when different characters share the same pronunciation. Our aim is to clarify name identification, especially in official contexts, and deepen understanding of Chinese culture, language, and naming conventions.

Yang uses trees for each pinyin name at the trunk and the actual names that compressed version might represent. Click on the leaves to hear the differences.

The folks up here received one of those loud emergency alerts a few minutes ago — for a “TSUNAMI WARNING.” I think that’s a first for me.

There was a 7.0 magnitude earthquake off the coast. It still amazes me that we can go to the USGS site and see that earthquake activity in real-time.

I check out Claude, a generative AI assistant to see if, how, and when such a tool could fit into an analysis and visualization workflow.

The network that connects the world still relies on surprisingly thin wires that run miles down on the ocean floor. Sometimes those wires break. For The New York Times, James Glanz, Elian Peltier, and Pablo Robles show the repair process and what happens when the internet doesn’t work.

Add another graphic to the baby name genre of visualization. Karim Douïeb put a spin on name trends by shaping the actual name to the line. Enter your name and see how many babies were given the name over time. Sometimes parents name their kid Santa.

Only the top of the vertically-sized letters represent the trend, with the bases below the zero-axis. I’m guessing that’s to keep names readable. Fun either way.

For Bloomberg, Jeannette Neumann describes the accounting error:

For years, Macy’s Inc. touted its ability to boost profits by cutting delivery costs and trimming other expenses on calls with Wall Street analysts. Then on Monday, the department store chain surprised investors by revealing that those very costs had become the source of an internal investigation into what the company has described as a multimillion-dollar employee plot to manipulate the metrics.

The retailer said the incident involved only one former employee, who had hidden as much as $154 million of delivery expenses since 2021. Cash was not taken from the company and the amount of hidden expenses is a small portion of the $4.36 billion of overall delivery costs incurred during that time.

The purpose behind the mistake is still under investigation, but I often wonder how many rounding errors in big companies were inspired by the movie Office Space.

Many hospitals in the United States are for-profit, which itself is not a bad thing, but problems arise when patient care suffers because of profit optimizations. For Bloomberg Businessweek, Caleb Melby and Noah Buhayar turn their attention to HCA Healthcare, the country’s largest hospital chain, and how staffing choices appear to appear to over-prioritize margins.

China exported next to zero vehicles in 2010, but from 2020 to 2024, China leapfrogged all other other countries to become the leading exporter, by a lot. For The New York Times, Agnes Chang and Keith Bradsher show the rise over time and the breakdown with unit charts.

Each car represents 10,000 exported cars in the above graphic. I like the 2022 Russia comparison for scale.

Is there a better gift than the gift of knowledge? No, there is not. It is the greatest gift that lasts a lifetime. Speaking of, you can gift a FlowingData membership to your friends, family, colleagues, and cats, and they’ll gain access to said knowledge from tutorials, courses, and a members-only newsletter. Or, treat yourself — an equally excellent idea.

Plus it’s Small Business Saturday Cyber Monday, which is totally a real thing and not made up at all, so you’ll be able to check multiple boxes off your list.

It’s super easy. Go to the membership page and select “Give as Gift” at the end of the page. You can schedule the gift arrival and include a message.

There are two options:

• Deviation — Visualization courses, tutorials, and a newsletter on process, backed by real experience and a human. Supports this independent site.
• Outlier — Everything from Deviation, plus a signed copy of Visualize This (2nd ed.) and supports this independent site more.

Thanks for considering this very small cyber business on this Saturday Monday. Your cat will love it.

To make batteries for electric vehicles, manufacturers require materials from all over the world. It’s not always clear how these materials are obtained. The Washington Post provides insights into the where and how with a set of maps and charts.

You know the John Snow map that highlights a cholera outbreak in London, from 1854. Alex Selby-Boothroyd made a 3-D-printed version that brings the stacked counts out of the map.

Daren Jannace animated 30 frames per day for one year and then put it all together at 30 frames per second. The full video, with audio captured on Daren’s phone during the year, is a 365-second video that represents a year in his life. It’s called 10,946.

Memento Movi, a mini-app by Michael Condouris, is what you get when you use movies as a progress bar for life expectancy. Enter your birthdate and expected lifespan. Then select a movie from the list. The percentage of your life that you’ve lived is translated to the percentage through the movie you would be, which gives you the frame in the movie.

I swear this was made just for me. [via Waxy]

Martin Wattenberg drew up a live visualization that shows colors mentioned in Bluesky posts, via the firehose. Just let the wave of calm wash over you.

I’m sure there are many more mashups to come, but I’ll probably shift anymore sharing to Bluesky itself, so as not to inundate you with a firehose about using the firehose. It’s just refreshing to see data flowing freely after companies moving the other direction over the past several years.

Here’s the good stuff for the month: things to use, things to poke at, and things to learn from.
