This example draws a smiling cat face as a static SVG graphic using React and D3 v7. The composition includes a grey circular head with purple outline, two white eyes with black pupils and orange ellipses, plus whiskers and a red mouth. D3's `arc()` function generates the curved mouth and ear shapes, while React renders the SVG elements. The code uses absolute coordinates and transforms to position the facial features symmetrically around the center of an 850×455 viewport.
