And Kai credits previous work from Jason Davies[0] and Mike Bostock[1]. Mike Bostock is the creator of D3.js and ObservableHQ.

On a side tangent, I find it crazy that the New York Times for a long period had yourself, Jeremy Ashkenas, and Rich Harris all on staff.…

You may already be aware of this, in which case I apologize for stating the obvious, but Mr. Bostock actually authored the comment you replied to. :o)

I about jumped out of my chair when I saw the username after posting

Jeremy’s here at Observable, too!

Huge fan of you both. Best wishes, and I get to go home today and tell the missus I engaged in unknowing dialogue with Mike Bostock, about Mike Bostock.

Based on a comment buried in the source, this library seems to be heavily based on work by Kai Chang: http://bl.ocks.org/syntagmatic/3150059 It’s a shame Kai isn’t created in the README, LICENSE, or announcement.

Thanks for the feedback, we'll fix this.

Parallel coordinates as known in d3 world and pointed out by Bostock! :)

Reminds me of some charts used by chemical engineers in the age of slide rules. Can anyone help me remember an example?

Don't know if it's what you're referring to, but psychrometric charts are always fun, and any of the thermodynamics charts (Pressure-Enthalpy being an example). The best part? You say the "age of slide rules", but these are still used today.

Not psychrometric...the ones I'm thinking of look exactly the same as this, but allow you to solve a system of equations by drawing a straight line between points on two columns, thus making the intersection of the line with the other columns your "answer" for those variables.

The scales are sometimes very strange, in order to achieve this effect.

These are known as https://en.wikipedia.org/wiki/Parallel_coordinates and are a pretty old technique. Although the wiki lists process control as one of the major users, their history has them as dormant until revived in their modern form in the 1960s, which doesn't quite match your timeline. Perhaps the discrepancy is resolved by whether parallel axes were used as a equation solving aid versus a visualization aid?

They're also not outdated, you can find them in many libraries, like highcharts here: https://www.highcharts.com/docs/chart-and-series-types/paral...

Excellent technical coverage is: Parallel Coordinates for Visualizing Multi-Dimensional Geometry, from 1987 at https://link.springer.com/chapter/10.1007/978-4-431-68057-4_...

Wikipedia links to this 1880 chart: https://www.davidrumsey.com/luna/servlet/detail/RUMSEY~8~1~3...

Ah, nomogram then?

Living up to your name! Thank you so much.

The ones I'm thinking of were "nomograms" (thanks to user 'chemeng'). Visually they look like perhaps a very specific subset of "Parallel coordinate" graphs. Definitely more for calculation rather than visualization. Evidently they were popular from around 1890 to at least 1950.
