Three concentric rings of colored disks rotate in opposite directions across three clusters, creating a dynamic geometric pattern. The visualization loads CSS named colors from a CSV file and renders them as pie-chart arcs using D3’s `pie` and `arc` generators. React manages state, while a `d3.timer` drives continuous rotation by updating the SVG transform of each ring. The inner and outer rings spin clockwise and counterclockwise, while the middle ring remains stationary, highlighting the contrast between the static and moving layers.
