Smiley
A yellow smiley face rendered as a static SVG circle with two smaller eye circles. The visualization uses React components to create the SVG elements, with D3 v7 loaded but not actively driving any data or behavior. The face is drawn with a yellow fill and black stroke, positioned at the center of a 960x500 canvas with a single smile curve implied by the main circle's arc. The example demonstrates basic SVG shape composition within a React render tree.
