This example renders a single static yellow circle with a black outline, centered on a 960-by-500 SVG canvas. It demonstrates the most basic structure of a Vega-Lite or React-based visualization, where the SVG markup is directly embedded in the HTML page. The code uses the React library for JavaScript logic, though it only imports and logs the React object, and the circle is defined using standard SVG elements (`circle`, `cx`, `cy`, `r`, `fill`, `stroke`) within the `index.html`. The styling is minimal, with a hidden page overflow and no interactive or data-driven behavior.
