A bright blue SVG backdrop frames a single yellow circle with a red outline, centered at the middle of the canvas. This simple shape suggests a face through its title, though no facial features are drawn. The example uses the D3 v5 `select` function to target the SVG element, then appends the circle with attributes for radius, position, fill, and stroke. The fixed dimensions of 960 by 500 pixels come directly from the HTML markup, and the page styling removes body margins and hides overflow for a clean, full-viewport display.
