New: I spent nine months creating a digital edition of The Naturalist’s Library, William Jardine’s 40-volume 19th-century natural history series. 1,300+ plates restored, 2.4m words, 27 posters, and 1 huge book. Explore: www.c82.net/naturalists-... How it was made: www.c82.net/blog/making-...
Homepage of The Naturalist's Library website, showing a grid of illustrated volume covers from William Jardine's 40-volume natural history series (1833–1843), with navigation links and a description of the digital edition featuring over 1,300 restored hand-drawn illustrations.A mosaic layout of illustrated species pages from The Naturalist's Library, featuring restored Victorian natural history engravings of animals including a zebra, giraffe, hummingbird, beetle, butterfly, fish, and bird, each accompanied by descriptive text and taxonomic details.A fan arrangement of printed reference posters from The Naturalist's Library, each displaying a grid of labeled natural history illustrations spanning birds, mammals, fish, and insects, fanned out against a sage green textured background.Photo collage of “Plates of the Naturalist's Library.” The left shows the green cover featuring a giraffe, deer, hummingbird, butterfly, and tropical fish against an engraved forest background. The right shows open spreads with restored illustrations of a giraffe, antelope, and parrots.

One of the fun parts of my job is working with @amberthomas.bsky.social to make visuals for USAFacts. Here are two I've recently worked on usafacts.org/articles/con... usafacts.org/articles/how... I'm on the lookout for new projects if you want to create a visualization or interactive data tool
A visual featuring calendars for the house and senate coloured to represent the length of a session on that day. 

Title: Explore daily time in session for the House and Senate from 2016 to March 2026.

Subtitle :Net time in session by first day of the session

Selected year is 2025

Annotated text: 

Feb 5 marked the Senate’s longest 2025 session, as Democrats held the floor overnight over Russell Vought’s OMB nomination

Both the House and Senate typically break over August. During election years they break over October as well.

The government shutdown lasted from Oct 1 to Nov 12. The House held only brief sessions during this time while the Senate met regularly
A visual featuring ribbons representing how long different groups spend in the different phases of the citizenship process

Title: Spouses of US citizens can become citizens themselves decades before siblings receive green cards

Subtitle: Time to citizenship by applicant’s country of citizenship and relationship to a US citizen, FY 2025

Steps shown:

File petition: US citizen applies to sponsor
Visa wait: Wait until a visa slot opens
Apply for residency:Apply for a green card
Resident: Green card approved; now a resident
Apply for citizenship: Apply to become a US citizen
Citizenship: Take oath; become a US citizen

Note: Timelines reflect the length of each step under FY 2025 conditions. Wait times are historical, not predictive, and shown sequentially for clarity. Immediate relatives include parents and children younger than 21. Citizens from countries highlighted separately experience longer waits due to the per-country visa cap. “Apply for residency” processing times reflect adjusting status in the US; comparable data for consular processing are not published.

having used claude extensively for the past couple of months, i think there is still a lot of value to understanding your code and steering it intentionally. the amount of incidental complexity claude accumulates otherwise (which mostly results in bugs that it can't ever fix reliably) is staggering.

I love these Ovechkin shot placement maps from @evolving-hockey.com & @theathletic.bsky.social Unfortunately, I can’t find the gift link button: www.nytimes.com/athletic/623... 📊#dataviz
Two perspectives on Ovechkin’s scoring from his "office" at the top of the left face-off circle:

The first is the position in the goal mouth, where they are clustered in the upper-left and upper-right corners, and along the left-hand post.

The second is showing the shot’s location on the ice. These form a blob extending from just below the face-off dot to a few meters above the circle. There is a concentration at the top of the circle’s arc that extends roughly the width of the circle.

Orange dots are one-timers, purple dots are "catch-and shoot" wristers. One-timers dominate the left-hand side, wristers the right.

I return to @johnnelsonmaps.bsky.social 's Silly Geographic Precision table whenever I see the coordinates in a file I'm trying to make smaller. Latest file was mapping atoms. uxblog.idvsolutions.com/2013/11/sill...
Here's a breakout of coordinate precision by the actual cartographic scale they purport:

Decimal Places
 Actual Distance
Say What?
6	10 centimeters	Your footprint, if you were standing on the toes of one foot.
7	1.0 centimeter	A watermelon seed.
8	1.0 millimeter	The width of paperclip wire.
9	0.1 millimeter	The width of a strand of hair.
10	10 microns	A speck of pollen.
11	1.0 micron	A piece of cigarette smoke.
12	0.1 micron	You're doing virus-level mapping at this point.
13	10 nanometers	Does it matter how big this is?
14	1.0 nanometer	Your fingernail grows about this far in one second.
15	0.1 nanometer	An atom. An atom! What are you mapping?

Nifty design: You can take advantage of left-to-right reading to tell a story with your labels. Here, FT could have put "They represent the working class" on the right axis next to other labels, but this layout causes you to focus on it *first*, and then pay attention to its decline.

It is fine to start your line chart axes at something other than zero, especially when small variations are important. You can give hints that your axis doesn’t start at zero by
placing additional space below the data, removing the baseline, and/or adding a broken axis symbol 📊 #VizTips
Two images of a the same line chart except the second one places additional space below the data, removes the baseline, and adds a broken axis symbol to the y-axis making it easier to notice the scale doesn't go to zero.

Describing this as a "technique to avoid misleading the viewer" feels like AI is misleading the reader. "It's a feature not a bug".

These were both great! (And lots of other links to read, too.) This bit resonated with me: “I have no idea what you’re talking about. I can read box plots just fine and so can the audiences for my charts.” Experts often don’t realize how much work it took to *become* an expert.

Stacked charts can obscure patterns in data. Only the first series and total afford easy interpretation. Unless those two are more important than the rest, consider breaking things up into multiple smaller charts to understand both proportions and patterns for each of your series.
