This example shows a minimal HTML page rendering a red-bordered circle and a filled black circle inside an SVG container, alongside a centered “Hello HTML!” message. It uses plain inline CSS for styling and JavaScript-free SVG markup to demonstrate the foundational building blocks of web-based visualization. The SVG elements are hand-coded with explicit coordinates and attributes, while the CSS rule sets the message font size and alignment. The example serves as a starting point for integrating interactive frameworks like React, as suggested by the linked starter.
