Hello HTML
This example demonstrates the simplest possible web page, rendering a single circle inside an SVG element. It uses a raw HTML file with embedded CSS and JavaScript to reset the body margins and hide overflow. The circle’s cx attribute is mistakenly set to the string “960/2”, so it does not compute the intended center coordinate, leaving the circle in its default position. The page relies on inline styles and no external libraries, serving as a minimal starting point for web-based visualization with SVG.
