SVG Fundamentals test
This example demonstrates fundamental SVG rendering through a static, self-contained HTML page. It creates two concentric circle shapes using raw SVG path elements with cubic Bézier curves, styled with red strokes and fills at varying opacity levels. The visualization also includes nested transformation groups and a clip path definition, showcasing how SVG handles coordinate transformations and shape clipping. The code relies entirely on native SVG APIs within the HTML markup—no JavaScript libraries or data sources are used—making it a minimal test of vector graphics capabilities in the browser.
