This example demonstrates a minimal HTML page that renders SVG shapes directly in the browser, including a circle, a navy line, and a blue circle. The code uses plain CSS for styling and JavaScript is not invoked; instead, SVG elements are defined inline within the HTML markup. It serves as a bare-bones starting point for understanding how SVG coordinates and attributes like `cx`, `cy`, `radius`, `x1`, and `stroke` work without any external libraries or frameworks. The page is entirely static, with no data source or interactive behavior.
