The HTML Canvas specification and the WHAT WG HTML specification define the Path object[1][2]. The Path and the CanvasRenderingContext2D objects share some graphics operations like: closePath, lineTo, moveTo, arc, arcTo, ellipse (not implemented yet), quadraticCurveTo, cubicCurveTo, rect [3]. But instead of an Canvas, the operations get applied to a Path object. Furthermore the object allows adding other Paths with transform. A Path object can then be drawn on a Canvas.
