This example demonstrates basic SVG shape construction using raw HTML and SVG markup. It displays overlapping red and green circles, a navy diagonal line, a filled path resembling a rounded bracket, and a black open path with sharp corners. The code uses standard SVG elements like `<circle>`, `<line>`, and `<path>` with inline attributes for positioning and styling. A commented-out `<rect>` shows an alternate shape, while the `<style>` block removes page margins and hides overflow for a clean canvas. The rendering relies entirely on native SVG, with no external libraries or data sources.
