If an image does not convey additional information, maybe it's just used to make the UI look more attractive, it makes sense for VoiceOver to skip it. UIKit: set isAccessibilityElement to false. SwiftUI: create a decorative image explicitly.
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.
Accessibility labels might not be the best input labels, used for example to find or interact with elements with Voice Control or Full Keyboard Access. In those cases, you can provide accessibility user input labels.
