Is this type of graph valid?

If you have text, you should be sure that the text is generic and can be modified. That is only for vector assets, the case. Pixel assets should not have text.

If you want to submit PNG files, get rid of the background.

And if you add text, be sure that is correctly spelled. Except if you use a language unknown to me, I would write your “cusine” as “cuisine”, which is French and means kitchen, but it also means the manner of cooking after a certain tradition.

These all have gibberish text - meaningless words with wrong spelling. Try to imagine what a Buyer would use these for... in short, they wouldn't.  

Hi @Recorridos virtuales 360 ,

The best way to know what will or will not be accepted other than being informed by the guidelines as they are posted on the Adobe website is to submit what you have. Assuming you have rights to the fonts and the names are fictitious, I believe you will need to include a property release indicating its your property. Otherwise the names will cause a refusal.

Best wishes

Submitted as is, these would never be accepted to Adobe Stock.
