Nothing says it doesn’t.
Nothing says it does either. And the name referring to “Graphic” and no mention of OLE is reasonably taken as an indication that it may not. I ask about it and you chastise me. Chill.
It says about replacement graphic. Please try to think about it. it is about to store or not to store a replacement graphic, not a “replacement for a graphic”.
I see: its description may confuse you?
Export replacement objects as fallback images for vector graphics
Ok, but that still doesn’t change it: the chart is a vector graphic.
