If your organization is required to meet web accessibility standards like WCAG then the “Accessibility Button plugin” is your ultimate solution.
The plugin would add an “Accessibility Mode” button to your dashboards. When clicking on the button - all the charts in a dashboard would be replaced with screen reader-friendly pivots.
The pivots were built according to top semantic HTML standards as described in this link.
