SVG Fundamentals
This example shows hand-coded SVG shapes rendered directly on an HTML page, displaying a green circle, a red outlined rectangle with a thick stroke, and a partially formed line element. It demonstrates fundamental SVG markup for basic geometric primitives. The code uses standard SVG elements like `circle` and `rect` within an inline SVG container, styled with attributes for position, size, color, and stroke properties. No external libraries or data sources are involved; it is a minimal static demonstration of vector graphics structure.
