Smile face part I
A static smiley face rendered in SVG, composed of a yellow circle with a black outline for the head and two smaller black circles for eyes. The example demonstrates basic SVG shape elements—`circle`—with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes, all hardcoded in the HTML. It uses no JavaScript libraries or data sources, relying purely on declarative markup within an inline `<svg>` tag. The minimalist layout serves as a clear introduction to vector graphics primitives.
