For every JSXGraph element, all [ARIA attributes](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA) can be set. In this example, a [screen reader](https://en.wikipedia.org/wiki/Screen_reader) will read the coordinates of *point A* when the point has the focus. The focus can be set with the `tab` key or with mouse click. The point may be moved by mouse, pen, finger, or arrow keys.
// Define the id of your board in BOARDID

const board = JXG.JSXGraph.initBoard(BOARDID, {
    boundingBox: [-5, 5, 5, -5],
    axis: true
});
var A = board.create('point', [2, 3], {
    name: 'point A',
    tabIndex: 0,
    snapToGrid: true,
    aria: {
        enabled: true,
        label: (self) => `${self.name} is at ${self.X().toFixed(0)} ${self.Y().toFixed(0)}`,
        live: 'polite'
