This example demonstrates the basic building blocks of SVG shapes in a static 960x500 scene. It draws a black-outlined circle, a yellow rectangle with a navy border, a diagonal navy line, and a black path with two segments. The SVG is embedded directly in the HTML markup, with the file named index.html. The code uses no external JavaScript visualization libraries, though the included index.js file declares a `main` function that writes an unstyled "Hello World" text into a container, but this script is not referenced or executed by the HTML document.
