Examples

Interactive examples demonstrating FuncNodes capabilities. Each example runs directly in your browser using Pyodide (Python compiled to WebAssembly).

Browser Execution

These examples run entirely in your browser. Initial load may take a few seconds as Python compiles to WebAssembly. Performance is slower than native Python installation.
