This example displays a simple yellow smiley face drawn with three SVG circles against a white background, using green stroke for the outline and black fills for the eyes. The face is centered within a fixed 900-by-490-pixel viewport, with coordinates hard-coded directly in the HTML markup. The code relies solely on native SVG circle elements embedded in an HTML document, requiring no external libraries or JavaScript. This bare-bones approach demonstrates the fundamental syntax for creating basic vector shapes and positioning them manually.
