Improve app accessibility

[Paulj1989]

Problem

Accessibility should be a central consideration when creating anything, and this should probably be even more of an emphasis for any NHS organisation! I've given quite a bit of thought to accessibility around the plots I've created (though I'm sure they could be improved), but there's lots of other ways that the app itself could be more accessible.

Proposed Solution

Add alt text to plots, tables (if possible?), and any other elements that could give meaningful feedback that users with vision issues would benefit from.

Alternatives

I suspect there's a bunch of different ways of doing this, and I imagine alt text is just one tool in a wider toolbox. I need to spend more time thinking about this and come up with other ways to improve the app's accessibility too.
