This example demonstrates SVG fundamentals by rendering a single circle element with a radius of 50 pixels, positioned at coordinates (50, 50) within an SVG container. The visualization illustrates basic SVG shape creation using the `<circle>` tag, with attributes for center coordinates (cx, cy) and radius (r). The code uses no external libraries or APIs—only native SVG markup embedded directly in HTML, showcasing the simplest possible vector rendering approach. There is no data source or interaction; the chart serves purely as a static demonstration of SVG syntax and coordinate system basics.
