This example shows a simple arrangement of primitive shapes—three circles and a rectangle—rendered directly in an SVG element on a plain HTML page. The shapes are placed at fixed coordinates with explicit fill colors, and the rectangle demonstrates an outline stroke. The code uses inline SVG markup within the `index.html` file, with no external styling or JavaScript. It serves as a bare-minimum introduction to SVG syntax, using only the native `<svg>`, `<circle>`, and `<rect>` elements.
