/**
 * Inspiration for this project found at:
 * https://markus.oberlehner.net/blog/pure-css-animated-svg-circle-chart
 * 1. The `reverse` animation direction plays the animation backwards
 *    which makes it start at the stroke offset 100 which means displaying
 *    no stroke at all and animating it to the value defined in the SVG
 *    via the inline `stroke-dashoffset` attribute.
 * 2. Rotate by -90 degree to make the starting point of the
 *    stroke the top of the circle.
 * 3. Using CSS transforms on SVG elements is not supported by Internet Explorer
 *    and Edge, use the transform attribute directly on the SVG element as a
 * .  workaround.
