Overview
Use this protocol when you want to create an accessible representation of a chart — a view that displays a graphical representation of a data set — for VoiceOver to play as an audio graph.
Adopt the AXChart protocol on your chart’s view model, and set the accessibilityChartDescriptor property to an AXChartDescriptor that contains all the semantic information you need to represent your chart through an audio interface, like the chart’s title, axes, data points, and a summary of the chart’s key takeaways.
