This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from SVG circles, with animated eyebrows that move. The code uses D3 v5’s `select`, `range`, and data joins to bind an array of five fruit objects to circles, setting position and fill attributes. The rendering is pure SVG, created through `.enter().append('circle')` on an empty selection. The eyebrows are implied through the data structure, though the visible output focuses on the static face layout.
