keyboard accessibility to c3.js tooltip

[poonamk]

How do we get keyboard access for tooltips of c3 charts.Tooltip comes up when we hover over the points in a graph. But is there a way to getting them using some combination of keys on the keyboard.

How would you get the x and y coordinates and which tooltip to show when the button clicks?

My assumption would be that in the case of keyboard access, the xy cordinates of the data point (not the cursor) would need to be used. The individual relevant data points would first need to be made keyboard focusable via the tabindex attribute.
