Let's make a face with D3.js!
This example creates a red SVG smiley face and animates its eyebrows to demonstrate fundamental DOM manipulation with D3.js. It uses `d3.select` to target the SVG element and applies styles directly, while the face itself is constructed through basic SVG shapes. The project relies on D3 v5, loaded from unpkg, and features a video tutorial embedded in the README. The eyebrows move via JavaScript-driven updates, though the specific animation logic is in a bundled file rather than shown in the visible source. The rendering is entirely SVG-based within a fixed 960×500 canvas.
