Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Visual Node Graph with ImGui
https://github.com/samuelmtimbo/unit recently, which at least uses some kind of hinted auto-layout (besides the more propriety fancy)
I really want to see more graphical coding for years, but node/graph-based and blockly seem to be the only approaches that got sone traction so far. So I like this thread and it seems at the right place.

Unit (Visual Programming System) [video]
Interesting, and clearly a lot of work's gone into this (60,000 lines of Typescript), particularly the UI, which is impressive (if, sometimes, over the top). I've been developing a similar system (http://www.fmjlang.co.uk/fmj/tutorials/TOC.html) and it's interesting to note the similarities and differences.
Similarities: code as directed graphs (less obvious in FMJ); can only connect outputs to units of compatible type; if and wait (looping is handled differently); sticky values; sliders. These design decisions are practically forced on you, but are often absent in earlier visual dataflow languages (e.g. Prograph, LabVIEW).
Differences: (1) inputs are named in Unit, ordered in FMJ (though they're named in formulas and edges can be labelled). (2) I experimented with automatic code layout but found this was too slow and not always what I wanted. Well done for getting this to work. (3) FMJ is now fully homoiconic - this maybe isn't a priority for Unit.
The Unit design philosophy is explained in https://github.com/samuelmtimbo/unit/blob/main/src/docs/conc... . This doesn't mention earlier approaches (e.g. the Manchester Dataflow Computer, Prograph) and it seems to be based on vaguely similar ideas developed more recently (Morrison's Flow Based programming; possibly React and similar systems for web development - I'm unfamiliar with these).
I have a number of questions:
(1) How does the type system work? Is it Dependently typed, Hindley-Milner, or something more basic? (FMJ is Hindley-Milner, with dependent typing partially implemented). How are new types be defined?
(2) How is the visual representation stored? One criticism I faced was that people wanted a readable textual representation which would work well with existing version control systems, a problem I have now largely solved.
(3) How are runtime errors handled?
(4) Is recursion supported? (I assume yes, but I didn't see any examples.) What about macros?
(5) What does Unit compile to? (FMJ has an experimental compiler where programs are compiled by running their source without evaluating their inputs, output is Lisp.)

A personal history of visual programming environments (2021)
I enjoyed reading this. I knew of quartz composer but I never did anything with it.
I love visual tools and I think they are underutilized today. I cut my teeth in ~2005 with Houdini[0] and Fusion[1] which are both heavily graph / node based (and procedural).
Most recently I have been rekindling my love for visual programming and flow based programming and plan to spend some time in January and February doing more research around flow based programming for infrastructure management.
I plan to get this sort of info published on my website which I have neglected for half a decade or more but if you are interested in visual programming you might enjoy checking these out:

Visual Node Graph with ImGui
you could compile this with imgui to the web: https://github.com/jnmaloney/WebGui
but you'd have to write communication to your django app. I would do that in JS and then pass events to the WASM layer.

My next app will be C++/Qt compiled to Javascript with Emscripten and then run inside Electron.
(Incidentally, someone made a Dear Imgui demo this way: https://jnmaloney.github.io/WebGui/imgui.html, minus involving Electron, of course.)
- Why it is that C++ can be compiled to JavaScript bytecode that is WebAssembly (using EMSCRIPTEN), but it cannot be compiled to Java Bytecode?
