This example demonstrates a single black circle rendered on a white canvas, showcasing the basic SVG shape elements. The visualization is created using raw SVG markup within an HTML `index.html` file, specifically employing the `<svg>` and `<circle>` tags to define the graphic. The circle is positioned with `cx`, `cy`, and `r` attributes, setting its center coordinates and radius. The entire graphic depends on the browser’s native SVG rendering engine, requiring no external JavaScript libraries. The work serves as a fundamental primer on declarative vector graphics, illustrating how simple shapes form the core building blocks of scalable data-driven diagrams.
