SVG-LF
This example shows a single, static circle rendered on an HTML page, demonstrating the basic setup for a web-based visualization. The SVG element contains one `<circle>` element with fixed `cx`, `cy`, and `r` attributes, all styled by minimal CSS that sets a message class. The page is built with plain HTML and JavaScript, using the SVG API directly rather than a charting library, and does not include any interactive behavior or data-driven rendering.
