SVG Fundamentels
This example displays a minimal set of SVG shapes—a black line, two filled circles, and a stroked rectangle—drawn directly in an HTML page. The illustration demonstrates fundamental vector graphics primitives and their attributes such as `cx`, `cy`, `r`, `fill`, and `stroke`. The code uses raw SVG markup within `index.html` without any JavaScript libraries or frameworks, relying on the browser’s native rendering. No data source is present; the visualization purely showcases SVG syntax and coordinate space.
