@CWOTUS The word “graphic” has that meaning, and it also has the meaning I quoted from the dictionary in my original answer above.
Text is not the same as graphicS, and it is not graphicAL, but it can be graphic (q.v. above).
Meanwhile, in Google Play Store land:
“Here are some examples of inappropriate text, images, or videos within your listing:
[...]
* Language inappropriate for a general audience. Avoid profane and vulgar language in your app listing. If it is a critical element of your app, you must censor its presentation within the Store listing.
* Graphic violence prominently depicted in app icons, promotional images, or videos.
[...]”
So while they do use the word graphic (which I would say is the meaning I quoted – meaning vivid) they are also referring to pictures. They also refer to text but not with the word “graphic”, but rather in other terms.
And my original reaction that it was censorship actually isn’t the case there, because they’re referring to the descriptive listing that people use to see what your app is, not the app itself. (Though it still makes me uncomfortable that the rules are unilateral and they reserve the right to not approve your app.)
