This example shows a static smiley face rendered as an SVG, composed of a yellow circle with a black stroke for the face and two smaller dark circles for eyes. The code uses plain SVG elements—`circle` tags with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes—positioned via hardcoded coordinates within a 960×500 viewport. It demonstrates a minimal React-free HTML page, relying solely on D3 v3’s SVG support indirectly through direct DOM markup, with no data binding or interactive behavior.
