A bubble game renders concentric, ray-defined circles within a grid of animated tiles. The D3 v5 code uses `select`, `range`, and `transition` to grow rectangles and multiple colored circles with differing radii, creating a layered effect. The SVG background is dark, and circles change fill color on hover via CSS. The visualization is driven by specified data arrays for levels, columns, and ball counts, with zoom support via `d3.zoom`.
