This example renders a simple SVG face using two large yellow circles for eyes and a smaller circle for the mouth, all drawn on a 960x500 canvas. The markup uses native SVG elements—`circle` with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes—placed directly in the HTML body. The styling applies a margin reset and hidden overflow to the page, while the SVG itself is static with no interaction or animation. The code demonstrates basic vector shape composition without any external JavaScript libraries.
