Smile 1
A yellow circle with a thick black outline is centered in an SVG canvas, drawn with React elements. The visualization uses React and ReactDOM to render a single `<circle>` element, with its radius calculated from the viewport height and stroke width. The code explicitly sets the fill color, stroke color, and stroke width to create the smiley face’s base, though no facial features are drawn in the active script. The rendering relies on SVG within a React component, with dimensions fixed at 960 by 500 pixels.
