This visualization displays three identical smiley faces rendered side by side, each composed of a yellow circular head with dark eyes and an arc-based mouth. The example demonstrates how React components structure the SVG output while D3’s `arc()` generator computes the mouth’s path data, defining inner and outer radii along with start and end angles. Each face is drawn with scaled radii and offsets, showing a simple reusable pattern for composing geometric shapes through layered `<circle>` and `<path>` elements within transformed coordinate groups.
