A simple face is drawn on a blank SVG canvas using D3.js selections. The example demonstrates basic shape creation with the `arc` generator from D3, though the visible rendering is a circle centered in the frame. The code sets the circle’s radius to half the SVG height and positions it at the center using `attr` calls, with the page styled for a clean, full-viewport display. It serves as a minimal introduction to binding SVG elements with D3’s data-join and attribute manipulation.
