path.arc()

path.arc(x, y, radius, startAngle, endAngle[, anticlockwise])

Draws a circular arc segment with the specified center ⟨x, y⟩, radius, startAngle and endAngle. If anticlockwise is true, the arc is drawn in the anticlockwise direction; otherwise, it is drawn in the clockwise direction. If the current point is not equal to the starting point of the arc, a straight line is drawn from the current point to the start of the arc. Equivalent to context.arc and uses SVG’s elliptical arc curve commands.
