Mouse follower
✓ Published0🌍 Public
A single black circle follows the mouse cursor across an SVG canvas. The circle’s position updates on every `mousemove` event, driven by React state. The application uses React’s `useState` and `useCallback` hooks to track the cursor’s coordinates and re-render the circle accordingly. The example is rendered with D3.js v6 for SVG creation, while React handles the interactive state, with no external data source.
