This example shows a minimal SVG circle rendered on an HTML page, serving as a foundational template for building data visualizations. It displays a single black circle at the top-left corner of the viewport, demonstrating the basic structure for graphical output. The code uses a simple HTML structure with inline SVG, the circle element, and uses no external JavaScript libraries or styling beyond default browser behavior. The implementation relies on raw HTML and SVG markup, providing a starting point for more complex projects.
