Can I make Domo visualisations accessible using a screen reader?

TL:DR; Is it a known thing that Domo Everywhere Embed Cards don't work well with screen-readers?

If I have a card, and I export it as a Domo Everywhere Embed Card, I can then embed it in a page as an iframe.

This is great as it makes it really easy to give a visual representation of my data wherever I need it.

I have a slight issue, though; when I try and use a screen reader to navigate through the visualisations, I'm not able to get anything much meaningful. Even for a relatively straightforward table, as it's rendered using a canvas element, the screen reader will only inform me that the element there is a 'Graphic Clickable'.

Is there any way to be able to use domo everywhere embed cards and have them be accessible?
