This example shows a simple cartoon face constructed with nested SVG circle elements. A large green circle forms the head, with white and black circles for the eyes, a red circle for the nose, and a yellow circle for the mouth. The static composition uses raw SVG markup embedded directly in an HTML file, with coordinates positioned along a 1000 by 500 canvas. The code relies on basic SVG shape elements—primarily `circle` and `line`—with attributes controlling fill color, stroke color, and stroke width. No external data source or JavaScript library is used; the visualization is purely declarative HTML/SVG markup.
