Why did it have to be pixelated in appearance? It would be far more attractive as anti-aliased vector lines and type.

The red highlighting reminds me of electricity in the classic circuit problem game _Rocky's Boots_ on the Apple ][.

As I've posted in similar discussions: https://news.ycombinator.com/item?id=42051536

The problem here, as always is that there isn't an agreed-upon answer for the question:

>What does an algorithm look like?

The problem is expressiveness of such a diagram is bounded by the size of a screen or a sheet of paper, and once one starts to scroll, or can't see the entire flow at a glance, things get complicated.

The node/wire programming folks have this a bit rougher to the point that there are sites such as:

https://scriptsofanotherdimension.tumblr.com/

I prefer to work visually, but not sure if that's actually valid --- unfortunately https://www.blockscad3d.com/editor/ doesn't support all of OpenSCAD and https://github.com/derkork/openscad-graph-editor has problems with a stylus (I have to leave the Windows Settings app open to toggle stylus behaviour which is enough friction that I don't use it as much as I would otherwise).

There are promising tools though: https://nodezator.com/ and https://ryven.org/ are very cool.
