A purple SVG canvas displays a face constructed entirely from D3.js shapes. The example uses `d3.select` to target the SVG element and applies a solid background color, creating the visual foundation. The face itself is built through D3's geometry and layout functions, though the concrete shape-drawing code is not visible in the provided snippet. The rendering relies on standard SVG elements within a 960×500 viewport, demonstrating basic D3.js styling and selection capabilities.
