This example demonstrates fundamental SVG shapes, including circles, a line, and a path, rendered directly in an HTML page. It shows how SVG elements are defined with attributes like `cx`, `cy`, `r`, `x1`, `y1`, and `d` for path data. The code uses plain SVG markup within an HTML file, styled with CSS to remove margins and hide scrollbars. It illustrates basic vector graphics rendering without any JavaScript libraries or data sources, serving as a minimal primer on SVG syntax and rendering.
