This example demonstrates a minimal SVG circle with no explicit positioning, centered by default at the origin. It uses plain HTML, CSS for styling, and SVG for rendering, with no JavaScript logic or data binding. The page serves as a stripped-down starter template showing how to structure a React-based visualization project, relying on core web standards rather than any charting or simulation libraries. The sole visual element is a circle with a radius of 100, rendered inside an SVG container.
