This example illustrates fundamental SVG shape elements—a rectangle, circle, and line—rendered within a fixed 960×1000 viewport. It demonstrates how vector graphics are defined declaratively in an HTML document using the SVG API, with properties like fill, stroke, and stroke-width controlling appearance. The code uses static coordinates and styles directly in markup, with no interaction or data binding. A simple CSS rule styles the page message, while the SVG itself relies entirely on built-in browser rendering.
