## What it is
QtNodes is a general-purpose C++/Qt library for building node editors with graph visualization and editing. It supports a dataflow programming paradigm where node algorithms propagate data through connections, and can run headless without a scene.

## Use cases
- build a node-based editor for my Qt application
- visualize and edit graph structures in C++
- create a dataflow/visual programming interface
- implement node graphs with automatic data propagation
- manipulate graph models headlessly without UI

## When to choose
- you are building a Qt (5.15+ or Qt 6) desktop application needing node/graph editing
- you want model-view separation with headless graph manipulation
- you need dataflow-style propagation between processing nodes

## When to avoid
- you need a web-based or non-Qt node editor
- your project does not use C++/Qt
- you need a ready-made end-user application rather than a library

## Facets
- artifact type: library
- maturity: active
- function: ui-components, graphics, data-visualization
- domain: developer-tools, graphics, cross-platform
- platform: cpp, windows, cross-platform
- tags: qt, node-editor, dataflow-programming, graph-model, model-view, qt6, visual-programming, linux, macos
