This package defines a wrapping functionality to create and manage mathematical node connections in Maya through Python scripting. The ease of access and method of using this will help to write readable and maintainable code for node based graphs that require a lot of mathematical processing.

Node graph framework that can be re-implemented into applications that supports PySide2 or PyQt5

Node Editor using ImGui

The visual node editor for nxt, a python layering and sequential execution tool for animation and VFX

I designed this Node-based interface as a way of learning Python and PyQt. It has been developed with Maya 2011 and only (as of now) works with Maya 2011. It's only meant to work with setting up particle systems. Some node functions aren't complete, but for the most part all of them are done.

Nodz : Visualize your data - Free nodes based graph generator.

A dependency graph written in python

A full open source 3D graphics editor in the browser, with scene editor, coding pad, graph editor, virtual file system, and many features more.

A graph node engine and editor written in Javascript similar to PD or UDK Blueprints, comes with its own editor in HTML5 Canvas2D. The engine can run client side or server side using Node. It allows to export graphs as JSONs to be included in applications independently.
