Yeah, I think I misunderstood the context. I understood/assumed it to be for an article/post you're writing, where you have something you want to say in general/some point of what you're writing. But based on what you wrote now, it seems to be more about how to caption an image you're sending to a blind person in a conversation/discussion of some sort.

I guess at that point it'd be easier for them if you just share the data itself, rather than anything generated by the data, especially if there is nothing you want to point out.
