This example displays a fixed yellow smiley face consisting of three SVG circles: a large yellow face with a black border and two smaller black eyes. The face is centered on an SVG canvas, with the eyes positioned symmetrically on either side of the vertical axis. The visualization uses React 18 and D3 v7, with the rendering handled through declarative SVG elements. The HTML file contains static circle coordinates and dimensions, demonstrating a simple vector-drawing approach without any interactive or data-driven behavior.
