This example animates the growth of a stylized flower with a green stem, pink petals, a silver center, and two leaves, all rendered inside an HTML container. It shows the flower’s construction before a black vase is added at the bottom. The code uses D3 v7’s `select` and `append` methods to build SVG elements, and applies transitions with `transition().duration()` to animate the petals and center from a radius of zero to full size. The rendering relies on SVG shapes like `circle`, `rect`, and `path`, with explicit pixel coordinates calculated from the container’s width and height. No external data source is used; the visualization is purely generated geometry.
