Fork of Let's make a face with D3.js!
This example demonstrates fundamental DOM manipulation with D3.js by rendering a smiley face with yellow circular head, black-outlined eyes, and an arc-based mouth. Animation brings the face to life as the eyebrows, drawn as rectangles, move upward and downward through chained `transition().duration(2000)` calls on the group element containing them. The visualization uses D3 v7 with SVG output, constructing the face within a centered `<g>` group and positioning features relative to the viewport dimensions. The code explicitly imports `select` and `arc` from the D3 library, with the mouth path generated using `d3.arc()` with specified inner and outer radii and angle bounds.
