When making charts accessible, sometimes you may have just too many data points for the user to have to go one by one through all of them. In those cases, you can create accessibility elements that represent meaningful chunks of the graph.

Sometimes you can create your own accessibility elements from scratch to group elements too. Perhaps because they're not contained in the same superview. You can combine these elements' frames and provide a suitable accessibility label.
Creating UIAccessibilityElements, combined with a semanticGroup accessibilityContainerType, can also help you make components as complex as charts accessible. Example from "Bring Accessibility to Charts" WWDC21: https://developer.apple.com/videos/play/wwdc2021/10122/
When configuring a largeContentImage or adjustsImageSizeForAccessibilityContentSizeCategory, it is important to use a pdf asset and preserve the vector data so the icons are crisp at any size.
