This example shows a simple yellow circle with two smaller black circles inside it, creating the beginning of a smiley face. The visualization is rendered as static SVG directly in the HTML, using primitive shapes rather than a data-driven approach. The code defines an SVG canvas of 960 by 500 pixels and draws three circles with explicit `cx`, `cy`, and `r` attributes: one large yellow circle with a thick black stroke, and two black circles positioned as eyes. No interaction or animation is present; the markup relies solely on standard SVG elements and inline CSS to set the page margin and overflow.
