A bare-bones HTML page renders a single static SVG circle centered on a 960×500 canvas. The page uses raw SVG elements—a `<SVG>` container with a `<CIRCLE>` child—defined directly in the markup, without any JavaScript or external libraries. The CSS resets the body margin and hides overflow, and the title labels the page “Hello HTML dr2o.” No data source or interaction is present; it demonstrates minimal inline SVG markup for a visualization gallery.
