This example demonstrates the use of raw SVG shapes within an HTML page, displaying circles and rectangles at specific coordinates. The code uses native SVG elements like `<circle>` and `<rect>` positioned on a 960×960 canvas, with some shapes colored via `fill` attributes while others remain default black. It applies basic CSS styling through an external stylesheet, including a `.highlighted` class and page-level body margins. No JavaScript libraries are used; the visualization relies solely on static SVG markup and Cascading Style Sheets for rendering.
