Shapes with SVG and CSS
This example shows a stylized face constructed from a yellow circular head, black eyes, rectangular eyebrows, and a curved mouth. The visualization demonstrates the animation of SVG shapes using D3.js and CSS. The eyebrows are animated with a D3 transition, moving up and down over a two-second duration. The mouth is created using D3’s `arc` function with specified inner and outer radii and angular sweep. The SVG canvas is 960 by 500 pixels, and the scene is centered using a group transform.
