A fork of the Hello HTML example by tuanpnguyen. It presents a single blank SVG circle with no visible data or interaction. The page consists of an HTML document containing an inline SVG element with a styled circle, though the circle has no fill, stroke, or coordinates, rendering it invisible. The code uses inline SVG markup directly in the HTML, with a minimal external stylesheet. No JavaScript libraries or D3 APIs are referenced in the provided files, and the visualization does not display any dataset, axis, or dynamic behavior.
