Playing with the ggraph package. There are some neat layouts available; I find the circle-packing layout is especially interesting. Here are the first four levels of Soil Taxonomy, with circle size proportional to "area mapped" in the US.

Soil depth functions that never were. Experiments with the beta distribution, R, a pen, and paper. Hard work done by an uneven surface and AxiDraw.

Fall colors in the Sierra Nevada, sorted according to perceptual distances (CIE dE2000) and divisive hierarchical clustering. R packages used: cluster, grDevices, ape, farver, aqp.

I needed something outside of politics for a few hours.
Adding family mineralogy classes (from Soil Taxonomy) to SoilWeb/STE in the next release. These are very broad groupings of soil minerals that can have profound effects on use/management.
kaolinitic (R), siliceous (G), smectitic (B):

Two levels of organization (horizon designation / moist soil color). Visually interesting, but harder to make and interpret that the standard (rectangular) treemap.

Experimenting with the {WeightedTreemaps} package for visualizing soil color proportions. Added the blue color for sanity check. Cell area proportional ~ soil color (Munsell) frequency. Positioning of colors is based on average human color perception of color similarity.

Great reference, thanks for sharing. You can imagine the damage caused by future runoff or dust.
You can "see" the Red Hills in imagery, or have a look at the local Soil Survey. Details in ALT text.

More soil colors, this time from the eastern edge of the San Joaquin Valley. East of Modesto, CA. These soil colors are from the detailed soil survey of the US. See if you can spot the valley--foothill interface.

Just some pretty soil colors, related to variability in parent material, drainage conditions, and sediment redistribution by water.

Found this beauty on a free book pile at the library. A little dated but a nice counterpoint to the genAI slop-coding nightmare.

I guess we were the clowns: we trusted GitHub was some kind of community for developers with an option for paid, professional support/hosting. Instead these assholes used our code to train bullshit machines which they are trying to force down our throats.
