SVG Tutorial
This example displays a minimal SVG scene with a single black circle centered near the top-left corner of a full-viewport graphic. It demonstrates the basic structure of an SVG element within an HTML document, using inline CSS to remove default margins and hide overflow. The rendering relies solely on the native SVG `<circle>` element with explicit `cx`, `cy`, and `r` attributes. No JavaScript libraries or data sources are involved; the visualization is purely static markup created for foundational SVG tutorials.
