This example constructs a cartoon face using SVG circles arranged with D3.js v5 in a React framework. It demonstrates basic SVG shape creation, grouping with `g` elements, and coordinate transforms through the `transform` attribute. The visualization shows layered circles for facial features, with both red and orange color variations, rendered directly in the browser without external data sources. The code includes a minimal HTML page with linked CSS and the D3 library loaded via CDN.
