A single purple flower with twelve animated petals and a yellow center grows above a green stem with two leaves, all set in a blue canvas against a brown vase. The animation uses D3’s `transition` and `attr` methods to expand petal and center radii from zero to full size over two seconds. Rendered with SVG primitives like `circle`, `rect`, `path`, and `ellipse`, the code builds the flower, stem, leaves, and vase directly via `select` and `append`. The static leaf and vase shapes use SVG path and geometry attributes without data binding.
