SVG fundamentals
This example shows a minimal SVG scene with a single blue circle, demonstrating the fundamental building blocks of scalable vector graphics. The code uses an inline `<svg>` element with a `<circle>` shape, positioning it via `cx`, `cy`, and `r` attributes and styling it with the `fill` property. It relies on plain HTML and CSS, with no JavaScript libraries or data sources, making it a pure static illustration of SVG’s core syntax. The rendering approach is direct SVG markup embedded in the page.
