This example shows a face constructed from a collection of SVG circles that respond to mouse movement. The visualization uses D3.js version 7 to manage the positioning and styling of these circles, which scale and shift based on cursor proximity to create interactive facial expressions. The code imports D3 via a CDN link in the HTML file and relies on CSS for basic styling. The face emerges purely from geometric arrangement rather than image data, demonstrating how simple SVG primitives can form a recognizable character through interactive dynamics.
