SVG Fundamentals
This example shows the fundamental building blocks of SVG rendering in a web page, displaying a single blue circle positioned at coordinates (100, 100) with a radius of 50 pixels. The code uses a bare-bones HTML document with an inline `<svg>` element to demonstrate how SVG shapes are drawn directly in the browser. It relies on standard HTML and the native SVG API, with no external libraries or JavaScript involved. The example serves as a minimal starting point for understanding SVG markup before moving to more complex visualizations.
