This example shows a simple red circle with two smaller black circles inside, drawn using SVG within an HTML page. The visualization is created directly in the `index.html` file using basic SVG elements like `<circle>` and attributes for positioning and fill colors. It demonstrates fundamental CSS styling, with the `.message` class setting font properties, alongside inline SVG rendering. The code does not use any JavaScript libraries or data sources, instead relying purely on static markup to produce the graphic.
