A simple line-drawing exercise builds a face from three SVG circles: a yellow head with a black outline and two smaller black eyes. The example demonstrates basic SVG geometry and styling using hard-coded coordinates and attributes like `cx`, `cy`, `r`, `fill`, and `stroke`. The HTML file references an external CSS file that resets the page margin and hides overflow. A linked YouTube video provides a tutorial for recreating the face, while the code itself uses only native SVG elements without any JavaScript libraries.
