Netron is a cross-platform neural network model visualizer that supports a wide range of deep learning frameworks (ONNX, TensorFlow, PyTorch, CoreML, etc.). It operates as an Electron desktop application, a web app, and a Python-based CLI/server. The architecture is modular: each model format is handled by a dedicated `ModelFactory` class implementing `match()` and `open()` methods, which parse binary or protobuf/flatbuffers serialized models into a uniform internal graph representation (Model -> Graph -> Node -> Value/Tensor). The application provides interactive graph visualization with SVG rendering, attribute inspection, and export capabilities. While primarily an application, it contains substantial data-processing code for format parsing, tensor decoding, and schema-driven metadata handling. The codebase is well-structured with consistent patterns, though it exhibits some duplication across format parsers and experimental/partial support for minority formats. The Python server (`server.py`) and the core binary parsing libraries (`base.js`, `protobuf.js`, `flatbuffers.js`) are independently reusable.
