This repository provides a reusable, interactive node editor library built on top of Dear ImGui. It is a pure C++ library with a public API that enables embedding a visual node/graph editor into any ImGui-based application. The core implementation handles node and link creation, dragging, selection, zoom/pan, context menus, cut/copy/paste, flow animations, and state serialization via a bundled JSON library. It is not a standalone application but ships with several examples and an application framework (Win32/DirectX11, GLFW/OpenGL) to demonstrate usage. The architecture is modular, with separate components for canvas rendering, bezier math, and JSON serialization, making individual parts reusable in other projects. The repository is well-maintained with active issue triage and recent commits, though it has medium technical drift due to heavy version-conditional code for Dear ImGui compatibility and reliance on some outdated dependencies (DirectX SDK, older stb versions).
