This example displays a simple, cartoon-like face centered on a violet background, constructed with basic SVG shapes inside a React component. The face’s mouth is generated using the d3.arc() API, which calculates a path from specified start and end angles, while circles form the eyes and nose. The entire graphic is centered dynamically using window dimensions and a SVG transform. The code relies on React for rendering and D3 v5 for the arc geometry, with styling defined in the index.html file.
