imgui-node-editor VS nuklear

Looks more like https://github.com/thedmd/imgui-node-editor/ to me - both are great libraries though.

I'm taking this low level node widget library: https://github.com/thedmd/imgui-node-editor

This sort of node graph?

It looks nice. If UI performance is a concern, one could move the GUI part to C++ and do some quick pybind11 Python bindings for better performance.

I've used this C++ ImGui node editor with similar features for some hacky synthesizer gui using this library: https://github.com/thedmd/imgui-node-editor

imgui-node-editor

Yes, I am looking for something like this https://github.com/thedmd/imgui-node-editor, but for C instead of C++

There are SDL2 renderers for Nuklear, if you can live with the OpenGL dependency, see: https://github.com/vurtun/nuklear/tree/master/demo

Nuklear

You might want to try Nuklear https://github.com/vurtun/nuklear or imgui https://github.com/ocornut/imgui , both to my knowledge have a Vulkan backend

In fact, if using a modern graphics pipeline with shaders, you will actually have to learn how to draw a single rectangle to your screen, and then use that knowledge to draw (anti-aliased) lines, rectangles, arcs, circles, ellipses, etc. too. For instance, have a look at https://www.cairographics.org/ https://github.com/vurtun/nuklear https://github.com/memononen/nanovg and https://github.com/nical/lyon. There are probably also tutorials on how to draw vectorized graphics using OpenGL, Vulkan, etc.

It looks really great. And there are examples inside demo https://github.com/vurtun/nuklear/tree/master/demo I should investigatevthat for sure. Thanks

P.S.: I know Nuklear has got a node editor, but this editor is only in an early stage of development and Nuklear development has pretty much halted since Vurtun left.
