This will be called once per identity of your View. It will not be run again unless the identity of your View changes. If you need to update the AXChartDescriptor based on changes in your View, or in the Environment, implement updateChartDescriptor. This method will only be called if / when accessibility needs the AXChartDescriptor of your view, for VoiceOver.
