If your `.whl` is not a pure Python wheel then open a PR or issue with [pyodide](https://github.com/pyodide/pyodide) to get it added here https://github.com/pyodide/pyodide/tree/main/packages. If there's enough popular demand the pyodide team will likely work on supporting your package, regardless things will likely move faster if you make the PR and consult with the team to get unblocked.

For example, NumPy and Matplotlib are available. Notice here we're using `<py-script output="plot">`

as a shortcut, which takes the expression on the last line of the script and runs `pyscript.write('plot', fig)`.
