Smiley Face
This example displays a static smiley face rendered as a yellow circle with two oval eyes, each containing a black pupil, and a curved mouth implied by the SVG shapes. Constructed with React 17 and plain SVG elements, the visualization uses hard-coded circle coordinates for the face and eyes, with yellow fill, black strokes, and thick stroke widths. The SVG canvas is set to 960 by 500 pixels, and the drawing is embedded directly in HTML without any interactive behavior or data-driven updates.
