// @function create(name: String): SVGElement

// corresponding to the class name passed. For example, using 'line' will return
// an instance of [SVGLineElement](https://developer.mozilla.org/docs/Web/API/SVGLineElement).

// Generates a SVG path string for multiple rings, with each ring turning
// into "M..L..L.." instructions
