Let's make a face with D3.js!
A face constructed from animated SVG line elements demonstrates how D3.js and raw SVG markup can build playful, expressive visual compositions. The example relies on D3.js v3 to generate and animate coordinated paths, with each line styled through CSS classes and applied stroke properties. The face emerges from a set of curves, using SVG’s `<path>` elements, coordinated via a force-directed simulation, while the overall canvas is set within an `index.html` file of 960x500 pixels. The rendering happens entirely in the browser as an SVG, with the `d3` script embedded directly on the page.
