This example shows a minimal HTML page that renders a single SVG circle on a 960×500 canvas. The code demonstrates the essential structure of an HTML document, using inline CSS to set the body margin and overflow properties, and JavaScript is linked for potential interactivity. The circle is defined directly in SVG markup with a radius of 200 pixels, though no fill or stroke is specified, resulting in a default black appearance. It serves as a bare-bones starting point for integrating CSS and JavaScript in web visualizations.
