This example shows the first stage of constructing a smiley face, displaying only a yellow circular head with two black eye outlines on an SVG canvas. The static SVG elements are defined directly in the HTML, with React 17 handling the page structure via UMD builds of `react` and `react-dom` from unpkg. The rendering relies purely on SVG circles with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes, while the embedded YouTube video demonstrates the intended progression. The face remains incomplete, lacking a mouth and pupils.
