Keyboard-Navigable Interactive Charts
Let users explore data points without a mouse.
Hover Is Not Enough
Interactive charts often reveal values only on hover. Keyboard and touch users never hover, so that data is locked away from them.
Make Data Points Focusable
Let users Tab to each data point or series by giving them tabindex="0". Now the keyboard can reach what the mouse hovers.
