A single static circle is rendered in the center of an SVG canvas, sized at 480, 250, with a radius of 250. The visualization uses D3 v5 to select the root SVG element and append a circle shape, setting its position and size through chained `attr` calls. The SVG canvas is fixed at 960 by 500 pixels, and the page includes minimal CSS to remove body margins and hide overflow. The example demonstrates basic SVG manipulation with D3, printing the canvas width to the console.
