SVG Fundamentals
This example demonstrates the fundamental building blocks of SVG graphics with a single circle element positioned at coordinates (50, 50) with a radius of 20 units. The code uses raw SVG markup embedded directly in an HTML page, defining the circle through its `cx`, `cy`, and `r` attributes. The rendering approach relies on the browser's native SVG support, with no additional JavaScript libraries or frameworks required. The example serves as a minimal starting point for understanding how SVG shapes are declared and rendered.
