This example renders an abstract, cartoonish face using React and D3’s `arc` generator alongside SVG shapes like circles, polygons, ellipses, and rectangles. The face features a radial and linear gradient background, a large circle with a thick orange stroke, offset eyes built from arcs and circles, and a mouth represented by an ellipse and a rounded rectangle. The code uses ReactDOM to mount the SVG, with D3 v7 providing the arc path for the left eye.
