This visualization shows three concentric circles forming the start of a smiley face, with a large yellow head and two smaller blank circles for eyes. The code uses raw SVG elements within an inline `<circle>` structure, setting the head at the canvas center with explicit `cx`, `cy`, and `r` attributes. Part I of a tutorial, it renders a static image with no interaction or animation. The SVG is drawn directly in HTML, using basic shape primitives without any external libraries or JavaScript, and the README notes this is "half way towards a smiley face."
