## What it is
NodeGraphQt is a node graph UI framework written in Python using Qt (PySide2), providing an embeddable node editor with nodes, pipes, palettes, and customizable widgets. It is designed to be re-implemented and integrated into desktop applications such as VFX and pipeline tools.

## Use cases
- build a node-based editor UI in a Python desktop app
- create a visual node graph for a VFX pipeline tool
- embed an interactive node editor with Qt
- implement a node graph framework with custom node widgets
- build a properties bin and node palette for a node editor
- prototype a visual programming interface in Python

## When to choose
- you need a ready-made, embeddable node graph editor in Python/Qt
- you are building desktop tools for VFX, media, or data pipelines that need node-based workflows
- you want customizable nodes, pipes, and widgets with MIT licensing

## When to avoid
- you need a web-based node editor rather than a Qt desktop UI
- your project does not use Python or Qt
- you need a full node-based execution engine rather than just the UI framework
