A generative flower animation rotates twenty blue ellipses around the center of the screen, with each ellipse’s radius and position smoothly expanding and contracting over time. The animation uses D3 v7’s `select`, `range`, and data joins to update SVG ellipse attributes, while a `setInterval` callback advances a time variable that drives a `Math.tanh`-based bloom cycle. The ellipses are rotated incrementally by equal angles to form a radially symmetric pattern.
