Mouse Follower
✓ Published1🌍 Public
A yellow circle follows the mouse cursor as it moves across an SVG canvas. The circle updates its position in real time through React’s `useState` and `useCallback` hooks, which handle mouse-move events. The example uses React and D3 v7, rendering the circle as an SVG element with coordinates derived from the `clientX` and `clientY` properties of the mouse event.
