Fork of Hello HTML
This example shows a yellow smiley face rendered as an SVG, composed of a circular background, two eyes, and an arc-based mouth. The face is built using React components, with each facial feature defined in its own file and assembled in the main `App` component. Dimensions and positioning are handled through constants, and the mouth’s curved path is generated using the d3 `arc` generator. The visualization uses React 18 and d3.v7, with SVG elements for all drawing.
