A bare minimum HTML page renders a single SVG circle with a radius of 400 pixels inside a 600-by-400 viewport. The example demonstrates the foundational structure of an HTML document with embedded SVG markup, showing how the circle’s size exceeds the canvas dimensions. The code uses no external libraries or JavaScript, relying solely on native SVG elements and the `circle` tag’s `r` attribute. It serves as a minimal starting point for creating static visualizations, contrasting with the linked React-based starter.
