Moving circle with mouse cursor
✓ Published1🌍 Public
A yellow circle follows the cursor across a 960x500 SVG canvas. The application tracks the mouse pointer's client coordinates and re-renders the circle's center position on every move event. Built with React 16.9 and D3 v5, it uses React's `useState` hook to manage the dynamic mouse position state, while SVG elements handle the visual rendering within a fullscreen, overflow-hidden layout.
