SVG Fundamentals
This example demonstrates fundamental SVG shapes on a static HTML page, including circles, rectangles, and lines arranged in a grid. The code uses raw SVG elements embedded directly in the DOM, with each shape positioned using coordinates and styled via attributes like `fill`, `stroke`, and `r`. A simple CSS-styled HTML message sits above the visualization. The page relies on native browser rendering of SVG without additional libraries or data sources, focusing solely on basic geometric primitives and their visual properties.
