This example displays the text "Hello SVG!" centered on the page, accompanied by a single circle rendered within an SVG container. It demonstrates the fundamental use of SVG elements and Cascading Style Sheets (CSS) to structure and style a simple graphic. The implementation is a bare HTML page that uses inline CSS for typography and layout, with the circle’s position and radius defined through SVG attributes. The example serves as a minimal starter for creating vector graphics on the web using standard markup.
