Smiley Face Part III
This smiley face visualization uses the D3 arc API to draw a curved mouth, combined with React for rendering and SVG for output. Yellow circles form the face and eyes, while a black stroke outlines the head. The D3 arc function generates the mouth path with specified inner and outer radii and angle constraints. This React and D3 hybrid approach demonstrates a simple geometric composition with code that imports React, ReactDOM, and D3’s arc module.
