Cope and Drag — CnD — Lightweight Diagraming Language wins awards

“CnD’s design is driven by cognitive science principles that influence spatial reasoning, visualization, and diagramming. It combines this with a bottom-up analysis that distills patterns from dozens of actual custom visualizations, and finds the two come together nicely. The resulting language is small, uses minimal notation, and can be used incrementally.”

New embedded Rust milestone!

I connected my electric guitar to ESP32 with an amplifier circuit and visualized the played notes with @ratatui_rs

Implement WCAG Rules in Your Infographics, by @a11ycollective:

There's a whole bunch of recent #ThingUmbrella updates which I still have to write about, but one of the things is the reworked, improved and more customizable optical flow (aka https://thi.ng/pixel-flow package). The visualization in this test video is showing it in action via color-coded overlaid flow field vectors (once again worst-case scenario for video compression, let's see how it comes out [or not...])

Just launched! The Real Image Height Comparison Tool from @Jushify.

Move beyond silhouettes and compare heights with actual photos for unparalleled accuracy. Upload your own pics or use our library. Great for creative projects, settling bets with friends, or just for fun.

Check it out! https://jushify.com/real-image-height-comparison-tool/

Winamp's visualization plugins transformed music listening into a psychedelic art form, with community created plugins like MilkDrop generating real time fractal animations synchronized to audio frequencies that became as important as the music itself for many users. Ryan Geiss's MilkDrop used sophisticated mathematical algorithms to convert audio spectrum data into flowing, morphing visual experiences, spawning entire communities dedicated to creating and sharing visualization presets with names like "Flexi's Mindblender" and "Unchained's Particle Storm." The plugin architecture exposed deep audio analysis capabilities, allowing developers to create everything from simple oscilloscopes to complex 3D environments that responded to bass drops, tempo changes, and harmonic content in ways that made every song feel like a unique light show. When Geiss open sourced MilkDrop in 2005, it led to ProjectM, a cross platform implementation that has kept the visualization dream alive across Linux, Android, and modern media players like VLC and Kodi. Today's streaming services prioritize convenience over customization, but projects like ProjectM prove there's still a hunger for the deeply personal audio visual experiences that made Winamp feel like a digital synesthesia machine.

A tiny bit of window dressing for the CLIM 2 spec's FORMAT-GRAPH-FROM-ROOTS. Which I use a lot because it is vanishingly little work, paste or type in some cons trees, voila, they merge matching symbols because I set that to happen, I can press a button to change the graphs, all great.

I could not even find my own previous articles and #demos of this online!

I used #uiop run-program to handle one specific case like

(gnuplot "bad title" '((1 2) (3 4)) '((5 6) (7 8)))
or equivalently,
(apply 'gnuplot "bad title" '(((1 2) (3 4)) ((5 6) (7 8))))

Do you personally have an example? I remember it being hard to dredge up gnuplot examples but this is beyond silly.

Interesting look at how to present #data and why one method works better -
