This example demonstrates foundational SVG shapes as a static composition. It shows a large blue rectangle, a red circle positioned at the left edge, and a green circle nested inside a separate `<svg>` element, all rendered directly in the DOM without a JavaScript library. The code uses pure SVG elements (`rect`, `circle`) with explicit `x`, `y`, `cx`, `cy`, and `fill` attributes to define geometry and color. The rendering approach relies entirely on static markup from the HTML file, with no data binding or interaction.
