Fork of Smiley Face Part III
This example shows a yellow smiley face rendered as an SVG, with black-outlined circular eyes and a curved mouth arc centered on a 960x500 canvas. Built with React and D3 v5, React components define each SVG shape, while the `arc()` generator from D3 computes the mouth’s path using specified inner and outer radii and start/end angles. Eye positions, radii, and stroke widths are set as constants, with the entire face grouped and translated to the canvas center.
