Fork of Hello HTML
This example is a minimal fork of the classic “Hello HTML” block, showing a single empty circle inside an SVG element. The page consists solely of a basic HTML structure with an inline `<svg>` tag, containing one `<circle>` element that has no visible attributes or styling. It serves as a bare-bones starting point for experimenting with D3 or other JavaScript libraries, illustrating how SVG elements can be embedded directly in a webpage. The code uses no external libraries or APIs, relying only on native HTML and SVG syntax. The data source is absent, with the rendering approach being static SVG markup.
