SmileyFace Pt1
A large yellow circle forms the face of a smiley, with two smaller black circles positioned as eyes on a plain SVG canvas. The example demonstrates basic SVG shape rendering using the `<circle>` element, with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. It shows how to compose a simple static illustration from primitive geometric shapes. The code uses no external JavaScript libraries, relying entirely on inline SVG markup within an HTML page. The rendering approach is direct SVG output with a fixed viewport size.
