Show HN: PathView – Visual simulation editor running Python in the browser

Operating in show hn launch, PathView – Visual simulation editor running Python in the browser operates.

Profile

I've been building PathSim, a Python framework for simulating dynamical systems (similar to Simulink). PathView is the graphical frontend - a visual node editor that runs entirely client-side.Python execution happens via Pyodide in a Web Worker. You drag blocks onto a canvas, wire them up, and hit run. The simulation streams results to live plots in real-time. You can also view and edit the generated Python code directly.No server, no account, no install. Everything runs in your browser.Some things that might be interesting from a technical perspective:- The simulation runs in a streaming loop at 10 Hz in the worker, decoupled from the UI render loop (also 10 Hz max). Results accumulate in a
