There is also the Vernier scale on certain styles of mechanical calipers.

I love the Vernier scales! But I honestly hadn't known about the sense in which slide rules have a Venier scale until your comment, which led me to [1]. In another class on laser-cutting I had students make a kerf-meter, which became more accurate with a Vernier scale.

Oh my God that is so clever. Thanks for sharing!

Slide rules are awesome.

Many irrelevant difference between programming languages are now exposed for what they are.

Thinking clearly is just as relevant or encumbering as it always was.

Wait until you hear about the pixel size restrictions on safari canvases.

WebGL punts to WebGPU for decent compute shaders.

That was also my research group's approach.

How else is the data going to make it to your phone?

And with a JS-friendly tool you can also test your plots on a tablet and a phone in your local wifi.

The API and ABI for this are tricky to get right.

Look at Stephen Few's website and books.

There is also ggplot, ggplot2 and the Grammar of Graphics by Leland Wilkinson. Sadly, Algebra is so incompatible with Geometry that I found the book beautiful but useless for my problem domains after buying and reading and pondering it.
