Seven colored circles of varying sizes and neon hues sit fixed on a pale green field, each gently orbiting its anchor point in a slow circular drift. The animation is driven by a continuous timer from the `d3-timer` library, updating each circle’s position with sine and cosine functions every frame. The visualization uses D3 v7’s `select` and join operations to efficiently create and update the SVG circles, with data defined inline as hardcoded coordinates, radii, and fill colors.
