A large yellow circle sits at the center of a blank SVG canvas, filling most of the viewport. The shape is drawn using D3 v5's selection and append methods, with its radius and coordinates set directly via the attr function. The code imports only the select function from d3, and the SVG element is created with unusually large width and height attributes in the HTML. The body has no margin and hidden overflow, so the circle appears as a simple, static geometric composition.
