Ships of the Gulf of México. Thought I'd try to overlay all of them on one viz this time. Probably clearer if I split them up, no? #rayshader adventures, an #rstats tale

I can now paint with #rayshader. This is with a mere ten samples. #rayshader adventures, an #rstats tale

Ships of the Mediterranean. #rayshader adventures, an #rstats tale

R: the language that sets the gold standard for dataviz! Anonymous user K. Midas says: "I love it!" (from a cheeky #rayshader figure in an upcoming blog post about rendering 3D plots with "golden hour" lighting by generating synthetic sunsets, entirely in #RStats with #rayrender)

This lo-res, firefly-ridden render of Brasil's power transmission lines (osm and derived) took hours. Turns out even with Tyler's amazing optimizations, I can still bring the rendering process to a crawl. To be fair, it's over 150k lines. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 26 · Transport. Yet another visualisation of global shipping density. But it's engraved on metal with realistic light and shadow. Because we can do that in R. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 26 · Transport. Take two. Ports of the Atlantic. Mostly. #rayshader adventures, an #rstats tale

Accidental aRt? A glitchy path-traced render of the world. #rayshader adventures, an #rstats tale

#30daymapchallenge | Day 22 Data: Natural Earth | The Great Islands Earlier this summer I finished this print version of my map from last year depicting our Great Lakes as islands. Been trying to learn more about lighting techniques in Blender—I think this was a big leap forward from 2024 version!

#30DayMapChallenge · Day 22 · Natural Earth. Many spinning globes. Honestly, I don't know how to use this amazing resource because I'm—no surprises here—not a cartographer. Am just a one-note guy who likes R. #rayrender adventures, an #rstats tale

#30DayMapChallenge · Day 21 · Icons. Lighthouses of the Pacific. Yes...I've done lots of lighthouse maps but not in this projection. I still like it—there's nothing like path-traced points of light realistically rendered. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 20 · Water. Bathymetric contours of the Tyrrhenian Sea. Why? I can't say...just felt like it I suppose. #rayshader adventures, an #rstats tale

Tree canopy height of Madrid. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 19 · Projections. Here's a visualisation of eight map projections. #ggplot2 adventures, an #rstats tale

#30DayMapChallenge · Day 18 · Out of this world. So here's valley networks of Mars. #rayshader adventures, an #rstats tale

Forest canopy height of Yellowstone National Park. #rayshader adventures, an #rstats tale

Forest canopy height of Zion National Park, Utah. #rayshader adventures, an #rstats tale

#30DayMapChallenge · Day 8 · Urban. Global urban areas. #rayshader adventures, an #rstats tale

Day 6 of the #30DayMapChallenge (3D), a render of Mount Rainier with a realistic atmospheric skydome generated w/ a lat/long/datetime, rendered entirely in #RStats with #rayshader and #rayrender! The atmosphere is annoyingly realistic: I now have to dial in the exposure depending on the time of day!

Tree canopy height of Paris, France. Have given up on #30DayMapChallenge. #rayshader adventures, an #rstats tale

Forgot to share this extra one for #30DayMapChallenge · Day 2 · Lines last night. Population density ridgelines. #ggplot2 adventures, an #rstats tale

#30DayMapChallenge · Day 2 · Lines. Bathymetry of the Atlantic Ocean as illuminated contours. #rayshader adventures, an #rstats tale

Forest canopy height of Grand Teton National Park, Wyoming. #rayshader adventures, an #rstats tale

#30daymapchallenge | Day 1 Points | Fall Foliage 🍁 We're at the tail end of autumn leaf color here in Madison. Here's a quick pair of maps to help you hunt down the most prevalent street trees that show off in vibrant yellows vs the less common but spectacular oranges and reds this time of year!

Day 1 - Points Rhode Island Lighthouses Most of my maps will be about Rhode Island. A good way for me to learn about a place (and find datasets) is to try to create a map of a thing. #30DayMapChallenge

Tree height map of Montréal. See the blank space without any trees in the middle? If you aren't from Montréal, what do you think that is? :) #rayshader adventures, an #rstats tale

Debated whether I should participate this year—a crisis of confidence and purpose and all that—but here I am again. #30DayMapChallenge · Day 1 · Points: Threats to global shipping as measured by anti-shipping activity messages. #rayshader adventures, an #rstats tale

Happy #rayrender Halloween indeed! @tterence.bsky.social inspired me to whip up an animation: a pumpkin made entirely in rayrender! (CSG for the carved pumpkin, extruded path stem, cyl + sphere candle, and r_obj eyes) Also, denoising made the below animation render in <3 minutes! #RStats

#30DayMapChallenge Day 1 - Points Elevation of populated places in the Greater Tokyo Area

A happy #rayrender Halloween to all who celebrate! #rayrender adventures, an #rstats tale

Crater Lake National Park, Oregon. #rayshader adventures, an #rstats tale

Continuing with forest canopy heights, here's one of Switzerland. #rayshader adventures, an #rstats tale

Forest canopy height of Yosemite National Park. #rayshader adventures, an #rstats tale

Forest canopy height of beautiful Shikotsu-Toya National Park, Hokkaido. I rather like how the mountains look like holes and are distinguishable from the lakes by looking at the way the canopy height changes. #rayshader adventures, an #rstats tale

Somewhere in the Andaman Sea. #rayshader adventures, an #rstats tale

Bathymetry of the Laccadive Sea. #rayshader adventures, an #rstats tale

This is the second year that I’m teaching a short session on Open Science and Reproducibility with Quarto, GitHub, and R for students in the European Doctoral School of Demography (EDSD) program (by @mpidr.bsky.social, @ined.bsky.social, @eaps.bsky.social). Materials: www.ekotov.pro/2025-EDSD-op...

A visualisation of forest canopy height in Shiretoko National Park, Hokkaido, two ways. Which do you prefer? I can never decide. What I can say is that Shiretoko is beautiful. And windy. And the sika are unafraid. Also, hot waterfalls. #rayshader adventures, an #rstats tale

A visualisation of the wine regions of New Zealand three ways. #rayshader adventures, an #rstats tale

Hive mind, please help me out! I need a more informative and explicit subtitle for my upcoming #RStats book "Model to Meaning" The premise is that analysts should often transform coefficient estimates into more meaningful / interpretable quantities like predictions, risk differences, slopes, etc.

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :( So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

Excited to announce my hands-on & in person workshop: "Introduction to 3D maps and data visualisation with Blender". You will learn how to create memorable 3D visualisations that stand out. #dataviz Register here: lu.ma/gtg2elht
