Eight red circles animate simultaneously along straight paths within a large circular outline on a white background. Each circle travels from a point on the circle’s perimeter toward the center, with staggered start times creating a rotating, pulsing effect. The animation uses SVG’s `animateMotion` element with the `path` attribute and staggered `begin` times, while the overall layout and styling come from static SVG markup with `mix-blend-mode: hard-light`. The example relies solely on native SVG animation, not D3’s JavaScript APIs.
