A first step toward building a smiley face with SVG, this visualization draws a yellow circle with a black outline as the head, then adds two smaller black circles for eyes. The SVG uses explicit `cx`, `cy`, and `r` attributes to position the head and eyes, with `fill` and `stroke` styling for colors. The code sets the viewport to 960 by 500 pixels using an inline `<svg>` element, and the eyes sit symmetrically around the vertical center, leaving the mouth for a later part.
