Let's Make a Face with D3.js!
This example uses D3.js v5 within a React framework to draw a simple yellow face on an SVG canvas. Circles create the head and eyes, while a path generated with the `arc` function forms a smiling mouth. The code demonstrates basic SVG shape construction and attribute manipulation, using explicit coordinates for the 960×500 viewport and D3’s arc generator to define the mouth’s inner and outer radii and angular sweep.
