Jupyter notebooks in 2024 is still not accessible.
In his #PyCascades talk, Venkatesh Potluri (who is blind) noted that popular Python libraries like matplotlib etc still can't embed alt text.
He made a patch for it, but the notebooks still don't pick up alt text.
@mariatta ALt text is definitely an issue and something needs to be done about plot accessibility, but VS Code works well enough as a screen-reader-friendly Jupyter interface. Speaking from personal experience here.
@mariatta Woah, Woah, WOUAH, WHAT, you are telling me you can put alt-text directly into PNGs?! This is brilliant, why do I only now learn about it! Well, now I have some coding to do…
@mariatta totally agree on the frustration, on the Matplotlib side the sticking point is that the maintainers don't have experience/expertise on accessibility. We'd love help on this - implementing to backend definitely seems reasonable, but we don't know what that should look like propagated up to public API.
