This example demonstrates fundamental SVG shapes and attributes within a single 900x500 canvas. It shows circles with varying radii and fill colors, a blue-outlined rectangle, a diagonal navy line, and a black, open path forming a geometric shape. The code uses raw SVG element syntax including `<circle>`, `<rect>`, `<line>`, and `<path>` inside an `index.html` file, with styling applied directly through presentation attributes like `fill` and `stroke`.
