SVG Fundamentals
This example demonstrates the foundational SVG circle element, rendered directly in an HTML document with no external styling. The code creates a single black circle with a center at (50, 50) and a radius of 50 pixels, using the `<circle>` tag inside an `<svg>` container. It highlights the basic structure of SVG markup for drawing shapes, serving as a minimal starting point for data visualizations. The page uses vanilla HTML and the SVG API, with no JavaScript or interactive behavior present.
