Smiley face exercise 1
A yellow smiley face drawn as an SVG appears on a white background. Two black circles form the eyes, while no mouth is present. The SVG is hard-coded in HTML with explicit pixel coordinates for the face and eye positions. The visualization uses raw SVG elements—`circle` tags with `fill`, `stroke`, and `stroke-width` attributes—rather than a JavaScript library or data source. The rendering is static and does not respond to interaction. The face is centered at 480 on the x-axis and 250 on the y-axis within a 960-by-500 viewport.
