Smiley Face Part 1
This example shows the first step toward building a smiley face, displaying a large yellow circle for the head and two black circles for the eyes on an SVG canvas. The code uses raw SVG elements—`circle` tags with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes—rendered directly in the browser. No JavaScript libraries are involved; the visualization is purely declarative markup, with the face centered at (480, 250) and a radius of 240. The page sets `margin: 0` and `overflow: hidden` to fit the graphic edge-to-edge.
