Fork of Fork of Fork of Fork Knowledge Smiley
This example shows a friendly yellow smiley face built from SVG arcs, with eyes, a nose, a mouth, and detailed upper and lower teeth. The code uses React for component rendering and d3’s `arc` generator to compute the path geometry for each facial feature, including separate arcs for lips and teeth. The face is centered on a 1000×700 canvas, and the project mixes static HTML, CSS, and JavaScript with the D3 v7 and React libraries loaded via CDN.
