Hello HTML
This example displays a simple static composition of three black-outlined circles on a yellow background, with a large central circle flanked by two smaller ones. The visualization is built using raw SVG elements embedded directly in an HTML page, with no external JavaScript libraries. It demonstrates basic SVG rendering by setting explicit coordinates, radii, fill colors, and stroke properties on circle elements within a fixed 960 by 500 viewport. The page uses minimal CSS to remove margins and hide overflow, focusing entirely on the vector shapes.
