This example shows a minimal SVG scene of three circles: a large yellow circle with a black outline and two smaller unfilled circles positioned inside it. The visualization renders directly in an HTML page using inline SVG elements, specifically `<circle>` tags with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes. The code defines a 960 by 500 pixel canvas and sets the page body to hide overflow. The page uses no external JavaScript libraries or data sources, relying solely on static vector graphics defined within the `index.html` file.
