This example animates a set of circles connected by a line, with the circles moving in a wave-like pattern. The number of circles oscillates between 5 and 15, and their vertical positions and radii change over time, creating a fluid, dynamic visualization. The animation runs at 60 frames per second using `setInterval`, updating the scene with each tick. It leverages D3’s `select` and `range` to generate data, and D3’s `line` generator to draw the connecting path, while react manages the updates through SVG elements.
