This example demonstrates SVG fundamentals using a series of concentric circles in grey, gold, and silver, accompanied by two curved paths animated with changing opacity. The static circles establish the visual structure, while the paths use SVG `<animate>` elements with `keyTimes` and `values` to create a pulsing effect over a 10-second loop. The code relies on native SVG rendering, with the animation controlled declaratively through SMIL. An inline JavaScript `console.log` shows the integration of basic scripting into the HTML page.
