Personally, I've found that any time someone declares that a given visualization "speaks for itself" what they mean is that they want you to not ask questions about it. Occasionally this is justified, but more often it's a stunt of some sort.
That said, did you consider the social and media context into which your work is being injected before you did so?
For example I would like to see the data for "Automotive Body and Related Repairers".
