This example shows a minimal SVG scene with two colored circles—one red, one green—placed against a plain background, along with a short black line segment. It demonstrates basic static SVG rendering in an HTML page, using native `<svg>`, `<circle>`, and `<line>` elements without additional libraries. The source code includes a separate stylesheet that removes the body margin and hides overflow, while the drawing itself is fixed at 960 by 500 pixels. No interactive behavior or data binding is present; the visualization simply presents geometric shapes with hardcoded positions and fills.
