SVG Fundamentals
This example shows a minimal SVG circle rendered inside an HTML page, serving as a starting point for learning SVG fundamentals with React and CSS. It draws a single circle at coordinates (50, 50) with a radius of 50 pixels using the SVG `<circle>` element. The page relies on plain HTML structure and CSS styling, with the SVG markup embedded directly in the document body. The code demonstrates the basic relationship between SVG coordinate systems and CSS-influenced layout, requiring no external JavaScript libraries beyond the React starter reference.
