This example displays a single blue circle with a black stroke centered within an SVG canvas. The circle is positioned at (430, 200) with a radius of 100, rendered on a 860×450 viewport using inline SVG markup in an HTML page. The visualization uses standard SVG elements and attributes directly in the markup, without additional JavaScript libraries or data sources. It demonstrates the fundamental structure of an SVG-based graphic embedded in HTML, serving as a minimal template for more complex visualizations.
