This example demonstrates basic SVG fundamentals by rendering two primitive shapes—a circle and a line—inside a 500×500 SVG canvas. The circle, positioned at coordinates (50,50) with a radius of 50, uses default black fill, while the line spans from (0,0) to (100,100) with a navy stroke. The code is a minimal HTML page that directly embeds SVG markup, relying on CSS and JavaScript only as referenced in the accompanying README. It illustrates raw SVG syntax without any external libraries or data sources.
