-Wheels are published for Linux x86_64 and macOS arm64 (Apple Silicon) on Python 3.11 to 3.13. Other platforms build the OGDF layout extension from source and need CMake and a C++17 compiler. Windows is not tested or supported; use [WSL2](https://learn.microsoft.com/windows/wsl/install), where the Linux wheel installs directly.
