Smiley Face MK1
A smiling face composed of simple geometric shapes is drawn in a 960x500 SVG. A yellow circle with a black stroke forms the head, while two smaller black circles serve as eyes, and a curved path creates the mouth. Built with React for component rendering, the visualization uses the D3 `arc` generator to define the mouth's inner and outer radii and angular range, with all elements positioned relative to a center point using SVG transforms.
