This is awesome!

Oh and OBSESSED with the design of the site. Truly 10/10.

Same! They also feel like 'simple' ideas because of their effortless execution.

How I figure out how far to dive into the topic ... well that's a bit of an instinct I've developed from doing this for years. But basically I try to keep the idea to a single take-away (ie: wealthy live in the shade!), and I try to keep it under about 1000 words.

It definitely does! Thank you so much. These rules of thumb are good to know. By default I work on two extremes; either a single chart or a long essay. This format is difficult to get used to (because it forces you to think about the core idea harder!), but definitely something I want to try.

I've been loving your newsletter so much! Always look forward to seeing a notification pop up in my RSS feed. If I may ask, how do you decide on what to write about and how far you'll get into it? It feels like any exploration can go on endlessly and scope feels tricky to nail for me.

This is awesome! I'm not a member (yet), but this would have been really cool to use. I also like that you describe what and how much is indexed. Semantic search can feel like a black box sometimes, so this offers some good hints at what is possible. Did you also look into Typesense for search?

data storytelling in lowercase - guest talk at Purdue | Aman Bhargava Thoughts on what it means for me to engage in data storytelling, in lowercase

I gave a guest talk at Purdue on intro to data storytelling in 'lowercase'. Writing it reminded me of when I was a student and thought only one kind of story, the Big Story, could exist. Some of this feels obvious to us in the #dataviz space, but maybe it isn't. Slides:

πŸ“£ NEW! I’ve just released the BIGGEST and perhaps most creative project I’ve ever worked on!

β€œSearching for Birds” searchingforbirds.visualcinnamon.com 🐀

A project, an article, an exploration that dives into the data that connects humans with birds, by looking at how we search for birds.

Introduction (Subtleties of Color, Part 1 of 6) - NASA Science The purpose of data visualizationβ€”any data visualizationβ€”is to illuminate data. To show patterns and relationships that are otherwise hidden in an impenetrable mass of numbers.

Looks like my full series on using color in #dataviz finally made the migration to the new NASA science website: science.nasa.gov/blogs/earth-...

If you’re new to visualization, or just want a refresher, it covers the basics of color theory, how to build a palette, plus some tips & tricks.

Journalism lost its culture of sharing. Here’s how we rebuild it The data are clear: The open-source culture that defined an earlier era of online journalism has collapsed.

πŸ—žοΈ Nieman Lab republished the piece Scott Klein and I put together analyzing the decline of open-source news.

If you haven't checked it out yet, here's another chance.

The Indian government released an MCP server that lets you query their survey data using plain English and get back aggregate statistics from national surveys. I explore some of its possibilities and limitations. #data #stats

Screenshot of rough flowchart sketch in TLDraw:

It has sections from start, learn, setup, build, deploy, master, to "stay up to date" and lists suggestions for each.

Started to feel like I'm gatekeeping it so I'll rather just share the draft: Last fall I started a opinionated Svelte 5 onboarding flow / roadmap. Plan was to translate it into an interactive (with links and more details) over Xmas but I had to take a hard break.
I'll probably go for it in February

Bluesky Map Interactive map of 3.4 million Bluesky users, visualised by their follower pattern.

I made a map of 3.4 million Bluesky users - see if you can find yourself!

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

RLHF has given AI models a quiet confidence in their ability to quietly demonstrate quiet strength through the quiet power of using 'quiet' quietly.

05.02.2026 13:25 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

A new AI-generated writing giveaway I've begun to spot is the overuse of quiet/quietly as an adjective. "Quiet intentionality", "quiet strength", "quiet revolution", quiet this quiet that; everything is quiet. Vague enough to fit anywhere and give a sense of understatedness.

Watching these points move like little insects crawling all over is amusing.

Btw this wasn't done with {camcorder}, but from the temp folder that Positron creates for plot renderings! tempdir() takes you there, then a bunch of ffmpeg commands to create the GIF.

chart titled "Sunlight & Water Requirements for Edible Plants" categorizes garden crops into three segments: Part Shade, Full Sun, and Part Sun. The chart uses distance from the center to indicate water needs, where plants closer to the blue core (like Ginger and Pea) require the most water, while those at the outer edges (like Thyme and Beans) have the lowest water requirements

#tidytuesday Week 5, I wanted to try visualizing the sun and water requirements of the various edible plants in this dataset. Maybe not the best idea, as I'm assigning jittered values to categories. coord_polar is always fun to use, serrated edges for a leafier look #rstats #dataviz

Woah, 700. Great to see it in the current state and can't wait to see it merged (whenever that is). It looks amazing and I'm sure it'll bring even more people into the Layerchart fold 🫑 Looking forward!!
