Hello HTML
This example shows a minimal HTML page with a single paragraph reading “Hello world” and an empty SVG canvas containing one unfilled circle. The page is built with plain HTML and embedded SVG, using no external libraries or JavaScript. The circle has a radius of 200 pixels but no fill or stroke, so it is invisible in the rendered output. The rendering approach is static SVG within the HTML document, with the circle’s properties left incomplete to demonstrate the bare structure of an HTML and SVG file.
