HTML5 Canvas Path Tutorial
To create a path with HTML5 Canvas, we can connect multiple subpaths. The ending point of each new subpath becomes the new context point. We can use the lineTo(), arcTo(), quadraticCurveTo(), and bezierCurveTo() methods to construct each subpath which makes up our path. We can also use the beginPath() method each time we want to start drawing a new path.
