This example shows a smiling face constructed from basic SVG shapes, including a yellow circular head with a dark stroke, two black eyes, and a mouth drawn as an arc. The visualization is built using React components to render the SVG elements, while the mouth’s path is generated with the `arc()` function from D3 v5. The code translates the drawing to the center of the viewport and uses relative coordinates for the features, with all shapes positioned programmatically based on constants for offsets and radii.
