Smiley Face part I
A static smiley face is drawn using two fixed-eye circles on a yellow circular head, rendered directly in an SVG element with explicit pixel coordinates. The sketch is a preliminary step toward a complete face, as indicated by the README note "Half way toards a smiley face." The visualization is built with React and ReactDOM, where the SVG markup is embedded directly in the HTML file rather than generated programmatically. Both the head and eye circles are styled with basic fills and strokes, showing a simple, hand-coded approach to vector graphics.
