This example demonstrates fundamental SVG shapes—circles, rectangles, lines, and paths—arranged with various fill colors, stroke styles, and overlap to illustrate basic vector graphics composition. The shapes include overlapping red, green, and blue circles, a yellow rectangle with a red border, a blue diagonal line, and two custom path elements. Rendered directly in HTML via inline `<svg>` markup with a 960×500 viewport, the visualization uses no external libraries, relying solely on native SVG attributes like `cx`, `cy`, `r`, `fill`, and `stroke` to control appearance and positioning.
