This example shows a cheerful, geometric face built from three SVG circles rendered inside an HTML page. The yellow circle serves as the head, with two smaller black circles as eyes, all drawn on a 950 by 450 canvas. The code uses plain React 18 via a UMD production build and directly manipulates SVG elements, such as `<circle>`, without any additional visualization libraries. It relies on static attributes like `r`, `cx`, and `cy` to position the shapes.
