This visualization displays a simple smiley face using basic SVG shapes: a yellow circle for the head and two smaller black circles for eyes. The code defines the elements directly in the HTML markup, using SVG properties like `cx`, `cy`, and `r` to position and size each circle. The head is centered at 480,250 with a 245-pixel radius and a 10-pixel black stroke, while the eyes are placed symmetrically at 350 and 600 on the x-axis. No JavaScript libraries or data sources are involved; it relies solely on static SVG rendering.
