Let's Make a Face Part I
A static SVG smiley face rendered as a simple data-visualization exercise. The code uses raw SVG circle elements to draw a yellow head with a black outline and two black eyes, positioned via explicit `cx`, `cy`, and `r` attributes. The face is centered on a 960 by 500 pixel canvas, with the head radius and eye coordinates manually calculated from the center point and stroke width. No external libraries or JavaScript APIs are used; the visualization relies entirely on declarative SVG markup in the HTML file.
