A network of colored circles groups into ten distinct clusters while a dynamic attract force pulls them toward the mouse position. The visualization uses `d3.forceSimulation` with custom `d3.forceAttract` and `d3.forceCluster` plugins to combine attraction and clustering forces, while `d3.forceCollide` applies collision avoidance. Nodes are rendered as SVG circles, and their radius and color encode cluster membership and size. The attract target updates on mouse movement, and collision strength ramps up over a three-second transition to create a smooth settling effect.
