What happened?

If following libraries were supported, the code would run normally I presume, and my automata diagram would be displayed but it seems visual-automata library does not work/is not supported.

What browsers are you seeing the problem on? (if applicable)

Chrome, Microsoft Edge

I haven't checked this, but i suspect you should take the error reason at face value (ie it really is going wrong because there's no pure Python wheel found) and if you resolve that you'll be fine.

If you take a look here, there are details of how to create a wheel yourself and then you should try importing that:
https://pyodide.org/en/stable/development/new-packages.html#determining-if-creating-a-pyodide-package-is-necessary

Btw we can guess at what your code did based on the traceback, but generally it's best all round if you can include it (or a minimally reproducible version if you can't post the full version)

This is happening because there isn't such a package in the pyodide ecosystem (which is what pyscript is using under the hood).

[TG721]

I checked pyodide packages. https://pyodide.org/en/stable/usage/packages-in-pyodide.html
Interestingly automata-lib library as I tested when I made my initial issue report worked fine with PyScript however visual-automata library did not. Both packages are not part of pyodide packages list. so why does one package work with pyscript and the other does not? perhaps because the other makes GUI output and first just terminal one? I don't know
