This example displays a cheerful, cartoon-like face constructed entirely from SVG shapes, centered on a yellow circle. Built with React and D3 v7, the visualization demonstrates how D3’s `arc` API generates a curved mouth path within a declarative component structure. The face’s features, including its eyes and smile, are positioned via computed coordinates passed to reusable `Eyes` and `Mouth` components inside a container that translates the drawing to the canvas center.
