Returns a list [[*x0*, *y0*], [*x1*, *y1*]…] of coordinates of the specified *event*’s pointer locations relative to the specified *target*. For mouse, stylus or single touch events, [*x0*, *y0*] is equivalent to d3.pointer(event, target). In the case of multi-touch events, the returned array contains a pair of coordinates for each of the touches.

For mouse, stylus or single touch events, [*x0*, *y0*] is equivalent to d3.pointer(event, target). In the case of multi-touch events, the returned array contains a pair of coordinates for each of the touches.

If *target* is not specified, it defaults to the source event’s currentTarget property, if available.
