Ep 14 Interaction with React

A simple face made of SVG shapes responds to the mouse in real time. The code uses React state with a `useState` hook and `onMouseMove` handler to track cursor position, then updates a blue pupil circle accordingly. D3’s `arc` generator draws the mouth path, while static black eyes and a wheat-colored face circle are rendered as SVG elements. The example demonstrates combining D3’s geometry helpers with React’s declarative rendering for interactive visualizations.
